Title: Attempted heating seat wiring loom... Disaster struck!
Post by: SeanyK on November 01, 2010, 06:17:13 pm
Hey folks,

Over the weekend I decided to fit ED30 front seats I had purchased, and bought a Kufatec heating seat loom & climatronic unit with heated seat function.

Let's just say over the last 2 days, it's been 'developing' between fitting the seats and getting the wiring loom under the mats etc, it was a case of spending a couple of hours, then going back, and in the case of yesterday, sod all thanks to the rain (need to have driver door open to get to fusebox etc!)

And so today, I had a day off work, and it would mark the day of wiring the electrical side of things up! (Fusebox area).

It was always the part I dreaded!

I went with the following in the end



Thick Red / White Wire - Fuse box port 37 (then fitted 30 amp fuse to this port for heated seats).

Thick Grey Wire - Fuse box port 44 (Then fitted 20 amp fuse to this port - it wasn't in use, according to the fuse guide its for 'Towing Recognition Control Module (not for rear battery)30a
) So hopefully it will work else i'll no doubt have to change the sodding thing lol.

Thin Grey Wire - Fuse box port 34 (Then fitted 15 amp fuse).



Unfortunately that sounds smooth sailing but it wasn't really... But this was the main problem, fitting the single white cable to the Central electrics module, Module 'C' Pin 1
Well, after trying to get the sodding plug out, I finally managed it, slid the pink pin locking thing out the way, and pushed the white cable pin in socket 1.
...Then I couldn't get the thing back in!!! I tried and tried, gave Lee (apollo13) a call and in my haste it looked like i'd put the pin in the wrong way round.

Well, could I get the thing out? No! I tried everything, paper clips, pins, flat mini- screwdrivers, nothing, in the end, I pulled the b*****d thing out with rage! And then used long nose pliers to pull the remaining connector out!

I did that, as I needed the car tommorow so I couldn't afford more time with daylight quickly dissapearing.

Anyway, I couldn't get the plug C back into the electronics module! Even then without the white cable! I checked for bent pins, nearly broke my back trying to look up there lol, but after lots of swearing, the plug went back on, although ironically, I now wonder whether that was always the case, and that the white wire may have always been in the right position, a lesson learned for me there - but a stubborn connector all the same.

So now, im left with it all wired in, bar that one white wire to the central electric module, i've cover the bare end with insulation tape and will seek out on Lee's advice a VW Repair wire (any part numbers for this anyone? Or is it something the parts guy SHOULD know?) and will put a new end on the white wire and try again.

I did a scan on VCDS afterwards just to see if it brought any fault codes, and all I got was this;


Address 09 : Cent. Elect.

1 Fault found

02092 - Enabling Heated Seat
   009 Open or Short to Ground


Assume this is just simply due to the heated seats being enabled in the CCM but not actually connected up?

So the theory behind all this is, IF I manage to get that white connector in the CEM, it should just all work...Providing those fusebox locations I've used are ok.

One thing I will say, is I noticed that the plugs on the seats, didn't neccasarily have matching pins, to the plugs in the wiring loom from Kufatec...I did order a 2007 loom for 2007 Seats though...?


A definate MASSIVE Thanks to Lee (Apollo13)  :happy2:for helping me out over the last weekend on the phone - much appreciated mate!!!

I bought the wiring loom for the heated seats. I tried to fit it. The instructions sent with the loom where rubbish for me. (Dont know if they have changed them). Asked on here for help but nobody had done it so no one was sure. Still havent got the heating fuction working, although the electronic adjustment now works fine.  :confused:

Hope you find a solution  :happy2:

Sounds like an interesting little project, I hope it works out.

I love these sort of jobs, they can be a real barsteward but when it works out there is a great amount of satisfaction.  As you found out though time is often against you.

Nothing to worry about mate, Id pull the additional fuses you put in to be sure though until you get it sorted.

Hi mate! I am pretty sure the ones on the seats, there was either less pins on the seat, than there was on the cable loom, or vice versa. Some lined up, other's didn't but I didn't take too much notice of that at the time, I figured, worst case, they can be moved fairly easily!

It's definately an interesting project! Amidst all the swearing if it DOES work after, it will be satisfying but not something i'd do again! :grin:

I had an extra pin or maybe two in the connectors on the loom from memory.

I tested them and they were permanent live so i can only guess they were perm power for the adjustment/ memory seat function (which i dont have).

I think kufatec probably only make one loom for all options heat/lumbar/adjust/memory and just try it on and charge you extra for something thats already there!!

 :fighting:

That I reckon, is spot on! After all, on their kit listings they list 2005,2006,2007.

According to that guide you posted up a few weeks back the connectors changed in 2007... So why have a 2006 option? It's definately them trying to confuse everyone!

Should my electric lumbar work? Without that CEM cable connected?

Post by: apollo13 on November 01, 2010, 08:26:48 pm
I think it should work, no reason why not mate.

You connected up the ground didnt you?

Post by: SeanyK on November 01, 2010, 08:32:00 pm
Hi mate, yeah I had 2 Brown Grounding Wires, so just undid the bolt by the driver side door (where the bonnet lever area is) put those 2 ground wires on to join the others, and tightend the nut over them.

I can't remember if I tried to use the lumbar, I was just glad to get back in the house lol, i'll try it tommorow morning though!
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: apollo13 on November 01, 2010, 08:37:18 pm
Well i cant see why it wont work mate.

To be honest youll set it and forget it if your the only user of the car, I change mine because me and the missus whos a short arse both use the car.

Oh you managed to get the bonnet release lever off!!  :fighting:

I snapped the bugger off! I've ordered another one, only a few quid  :grin: I was getting impatient!
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: SeanyK on November 02, 2010, 09:21:19 pm
Well the electric lumbar works...  :grin:

Just need the repair wire to fix the CEM Wire and hopefully we jammin!

Post by: SeanyK on November 02, 2010, 10:22:38 pm
The pin connector is square for the CEM, so I reckon it was in ok all along :( Just the connector is a bitch to connect up, I think that's just how it is, oh well, live and learn and all that!

Now I just need to wait for the repair wire and hopefully that should be it!

The fact the lumbar works is a good sign hopefully that the wires are as they should be...
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: apollo13 on November 02, 2010, 10:45:21 pm
Im sure itll be fine mate, I ordered all my repair wires and connectors today should be here thursday.

At least youll know how to do it for next time!  :rolleye:  What sensors did you go for in the end?
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: SeanyK on November 02, 2010, 11:01:28 pm
Very true... That's quite good, 2 day turnaround on parts...I ordered some bits like bonnet lever etc that should be here Thursday too then (in theory!)

Went for Steel-Mate sensors PTS400 were the model number - they look good, will get a pic up when I can be arsed to clean the car!!! :grin:

I have no idea how to use a multimeter, but I put it on 20V and prodded that connection between CEM and White wire, and it gave no readings just 0.

Post by: apollo13 on November 03, 2010, 09:08:03 pm
Look up the fault codes here mate  http://wiki.ross-tech.com/wiki/index.php?title=Category:Fault_Codes&until=16946%2FP0562%2F001378

Probably mostly battery related. The hvac and cecm ones are because your not fully connected up yet.

The radio is because youve got an aftermarket headunit.

Is the plug you took out back in the cecm? Nothing else disconnected mate?
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: SeanyK on November 03, 2010, 09:11:24 pm
Do you reckon the CEM connector I used earlier was no good then? The wires are joined etc, and the pin, whilst not the same as the original pin, seemed to fit well enough.

But I guess the fact the multimeter showed 0 when touching the bare wires crossed together means no power getting to them? ( I tried putting the black connector, the red connector, and finally both on the wire - still no readings).
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: apollo13 on November 03, 2010, 09:14:22 pm
So youve repaired the wire you broke and your all connected up now??

Somethings not right there mate if your all connected up!!

You need to check the slots youve put the new fuses into in the fuse box have power and are not just empty slots!!!

Take the fuse out and test the top terminal ( the one where the top blade of the fuse goes in) with the red lead on the meter and put the black lead on a ground point as your doing it. You should have 12v either with the ignition off or on depending on what your after.
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: SeanyK on November 03, 2010, 09:18:47 pm
There was just 1 wire left mate, which was that white wire going to the CEM Connector C Pin 1.

A VW Specialist gave me a connector which was not the same pin type connector, but said to try it (he had soldered some wire onto it also so I could just join it to the end of the white wire).

I twisted the wires round each other, good connection, but still no joy.

So it could be either something else not right (maybe the seat pin connectors?) OR it could be that the PIN connector he gave me isn't OK to use, and it has to be the exact type of pin?
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: apollo13 on November 03, 2010, 09:29:36 pm
Shaun I take it there not heating up??

Have you tried clearing these faults? They might be lingering from when youve unplugged everything.

That new connector might be shorting out something in the cecm.

To be honest without seeing it all its hard to say mate sorry.
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: SeanyK on November 03, 2010, 09:41:50 pm
Hi mate, yeah I know what you mean I think I may have to take you up on that offer to have a look! Although my friend lives near Bromley (if that is anywhere nearby?) And i'll probably be around that way at the weekend with her if thats any closer than lakeside? (I can drive over).

Should there be a voltage on that wire? Prodding a multimeter into it surely would reveal some sort of current if it was active? The seats not heating up or anything.

I think I can ignore all the other errors, even after clearing, they come back, but I think the battery is a bit low which is understandable so will cause the others.

But the open circuit on the heated seats, is the same as when the pin was not even connected... So probably that connector is totally wrong (it pulls out very easily when you undo the locking tab - a stark contrast to the pain in the arse it was to get th e original pin out!)
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: apollo13 on November 03, 2010, 09:44:24 pm
Check all your wiring again mate.

Youve got one extra wire to the fusebox thats for your lumbar feed.
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: vRStu on November 03, 2010, 09:49:42 pm
That says to use fuses 4 and 37 with 37 being a mighty 30A.  Are you sure you've got this correct??  What does the manual say are the heated seats fuse assignments?
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: apollo13 on November 03, 2010, 09:54:09 pm
The thing is Stu as i found out when i did mine is that the fuse layout in the hand book doesnt always marry up with the layout in your own fusebox.

As long as he has the corrrect rating of fuse and the location is either permanent feed or ignition feed it shouldnt matter?

Shaun the 'thin grey wire' youve put on a 15a fuse needs to be on a 5amp. But that wont change anything as far as getting it all to work.

Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: SeanyK on November 03, 2010, 09:55:38 pm
I had to move the electric lumbar adjustment wire (big thick grey one) to another socket, as i'd made a mistake with that, but fixed that last night - that works no problem, it works without keys in the ignition.


This is what i've done;

Thick Red / White Wire - Fuse box port 37 (then fitted 30 amp fuse to this port for heated seats) - The various fuse layouts all seem to suggest this is for heated seats, so I just went with that one.

Thin Grey Wire - Fuse box port 34 (Then fitted 15 amp fuse).


There were no extra wires Lee mate? All I had is hooked up, out of memory it was;

2 x Seat Connectors (Passenger/Driver)

1 x Batch of 3 wires (to go to climatronic module rear)

1 x Batch of 4 wires (3 above to fusebox, 1 to CEM)



Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: apollo13 on November 03, 2010, 10:04:24 pm
The only way to tell is to test continuity/power at the connectors under the seats.

It all 'seems' as if its all connected up right but hard to tell sitting at a keyboard!

Are you def sure those seats were 2007? the looms for pre 2007 are totally different.
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: vRStu on November 03, 2010, 10:07:33 pm
It does matter where you connect to in the fuse box, you can't just go pulling 30 amps down the nearest live wire.

You need a Terminal 30 (Output directly from battery positive) or 30a (Output directly from battery positive (behind fuse))
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: SeanyK on November 03, 2010, 10:11:39 pm
The ED30 I *think* only came out in 2007 so I was guessing it must be either 2007 or 2008 seats that I bought.

Maybe a pin or two needs moving from the actual seat connectors, but it seems odd the electric lumbar works fine?

Stu - Im pretty sure fuse 37 has a direct output? It does seem thats the fuse everyone tends to use for heated seats?

In this situation I am more than willing to be proved wrong though! (And hope I am!)
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: apollo13 on November 03, 2010, 10:13:39 pm
Yes Stu but Shaun has the mighty 30a is in fuse slot 37 which is the right one.

As is mine, its the others I was really referring to mate. But Shaun you do need to move the 'thin grey wire' out of 34 and put it on a 5a fuse.

Do you think by moving it from 34 and putting it on a 5a it may solve it?

Im not saying it will solve it but it needs to be moved!

You need to follow the diagram link i sent you unless the fuse positions stated are already taken up (like they were on mine but i had many more wires to terminate).

I just hope nothing is damaged mate, If you look at the diagram you can test the pins in the connectors under the seats to see if youve got 12v pins 4 and 10 on the drivers and 10 on the passenger.

Also check the wire that goes to pin 12 on the climate panel has got 12v

I lied it uses a terminal 15 supply. Switched positive behind battery (output contact from ignition/starter switch)

Ok here are some connections for a 2005 MY Golf with Seat Heating -

Fuse 37 is the 30a supply.  This is fed to pin 5 of the plug under the drivers seat T6g and pin 5 of the plug under the passenger seat T6f which connects to the heated seat controllers.

Fuse 4 is a 5a supply.  This is fed to pin 1 of the plug under the drivers seat T6g and pin 1 of the plug under the passenger seat T6f which connects to the heated seat controllers.

Both of these appear to be via 10 pin connectors T10a and T10b respectively, under the seats.  Do you have 4 pin connectors (T4l)?  These appear to take care of the ground side of things.

T6g/4 and t6f/4 is a ground from the seat control unit

Did you get instructions from Kufatec?

Cheers Stu, My seats were 2005 and the wiring set up is different to the 2007 and later as shown here

http://3.bp.blogspot.com/_y2Yifl1vjns/S4NPnf8QwLI/AAAAAAAAD2E/LniPqs0x2hE/s1600-h/Heated+Seats.jpg

These instructions arnt from kufatec but are much easier to understand IMO than the kufatec ones.

I think Shaun has it sorted now but Ill leave that down to him to tell everyone about it!!!!!!!!!!!!!   :grin:

Sorry mate had to say something!

I would just like to add...

I don't mind self nominating myself for the forum numpty of the month (potentially YEAR) award...

But I haven't actually plugged the seat connectors in...! :ashamed: :ashamed: :ashamed:

I've been so preoccupied worrying about airbag connectors, wires here there and everywhere, I didn't actually plug the connectors from the Seats' themselves into the loom!

Will do it tommorow after work and report back!

VERY EMBARESSING!!! :laugh:

Sean I don't think thats too bad for your first biggy retrofit? Leaving some thing out like the plugs is easy done...don't beat yourself up about it get out there and sit in it all night knowing you made that happen :grin: :happy2:

Only joking don't go out all night :grin:

You'll have the car fully loaded soon mate no worries. To be honest you've probably done the biggest pain of a job on the car for retrofits imo.

Well done :congrats:

Darren

Hi Darren, thanks mate - I still feel a numpty, if I plug it in tommorow and it all works, I will be very very happy but still embaressed!

I just wonder how long it would have taken to finally click... As it's only when Lee said "check pin x on the seat for volts etc" when I thought ... hmmm I don't remember plugging the connectors in!

I spent ages tidying the wiring, making it all neat, clipping the connectors on the existing carpet mounts etc, and then didn't plug the things in :grin:

Some potentially good news then - Fingers crossed.

They were connected in the end :(

Im meeting up with Lee tonight to look at this!

Stu / Darren >

Lee very kindly had a look at the wiring today, he fixed up the CEM wire and a bent pin, and moved one of the incorrect fuse box locations to a correct one.

He then used a multimeter, and when turning the heater controls to 5 the voltage was 14v ( I think? Or it might have been 16v) and when I turned heat seat controls down, it went down to 0. So the signal was getting to the loom under each chair.

After all this, and many of Lee's testing out the wires he has worked out that it the Kufatec wiring is for a LHD car... And that the passenger seat connector, should in fact, be the driver seat connector, due to the differing amount of pins.

Thats certainly what it looks like, and funnily enough, when plugging in the wires behind the climatronic panel, I ignored Kufatecs suggestion of Pin x for driver Pin x for passenger side, and reversed it, and lo and behold each heated control went to the relevant side... So it's all geared for LHD = Lee had the same issue when connecting his, only difference was the 2005 wiring looms are identical each side, so it didn't matter which plug went to that seat etc.

Stu, do you happen to have any wiring diagrams for the 2007+ Seats connectors?

Sean I've sent the diagrams to your profile email address.

Thanks Stu, much appreciated mate,  Lee is kindly going to help tommorow extend the wires and swap the Seat connectors over and hopefully, that will fix it!
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: SeanyK on November 05, 2010, 01:32:49 pm
I am also complaining to Kufatec about this, it doesn't state anywhere about LHD on their website, and as Lee said, for vehicles 2005 & 2006 the wiring is the same for passenger and driver side on the connectors, yet for the 2007+ seat wiring the drivers seat holds the control box so needs the main adaptor.

If this does work it will help anyone in the future when buying Kufatec looms for post-2007 car seats.

Just to add, I think and from what I have read the change happened from 2007 but they maybe a crossover somwhere in late 2006.

If anyone is thinking of doing this mod then check the seat plugs before you order any wiring. Dont just rely on what your told by the seller or breakers yard!!
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: vRStu on November 06, 2010, 07:55:25 am
The wiring diagrams say it was 2006 onwards but I don't know what month.
Title: Re: Attempted heating seat wiring loom... Disaster struck!
Post by: apollo13 on November 06, 2010, 10:54:34 am
I think the only way to be sure Stu is to look at the seat connectors and check the number of pins.

If the drivers and passenger connectors have and equal number of pins then go for the earlier loom, if not then the later loom.

I have 2005 car with 2005 seats and even when i connected mine up I had to swap the control wires around behind the climate panel because they were the wrong way round. This leads me to believe that the loom was geared up for a LHD car.

Hi guys! Success today!

The 30amp cable I needed for 2 of the wires arrived yesterday - and I had booked today off work for that very reason of fitting it all.

Armed with a couple of reels of Halfords 7amp cable in various colours, a brown earth cable, and 10M (!) of 30amp cable, I set about removing the driver & passenger seats once again, starting by feeding the long passenger side loom back to the driver side, then chopping the driver side connector leaving approx 4 inches of cable still attached to the connector.


I did this the long way round, but having a couple of wires the same colour for 7 different wires I couldn't do them all at once, so I had to do them one at a time, feed one wire through from one side to the other, then join it at it's respective connection, this did take a while, and is a pain in the arse but it was the only way to be sure the right wire was going to the right connection.

I had my dad helping for a bit as well which helped out, but we did a combo when it came to connecting the wires, for some, we crimped bullet connectors on, for the thin wire, the crimps were too big, so we did the old fashioned wrap the wires round each other, solder and cover.

Anyhow, after all that, im happy to say it works perfect, and is far neater than i'd done it before, as now you literally cannot see any wires anywhere.

Lee > Thanks very much for your help with this mate again it's been a huge huge help! Guess what, bizarely, the heater control panel controls the correct seat! (Remember last week I said it was doing the opposite?) so either I connected the 2 red/white wires on the loom in the wrong pins and thats miraculously fixed it or I was imagining things last week instead!

Either way... A toast to you all!


I also fitted Passat CC Window switches, mirror switch, and headlight switch will post another thread about that with pics this weekend.

Just for reference for anyone who searches this thread in future.

IF you are retro-fitting heated seats on seats from a 2007+ GTI then you MUST reverse the wiring loom.

In otherwords, what you THINK is the passenger side (a big cable on it's own) is actually the DRIVER side connector! So be prepared to extend wires!

Woooo Hoooooo!   :pomppomp:

Well done mate you got there in the end! Just in time too, its freezing!

Well Im glad my bit of trouble shooting in Bluewater car park at ten o'clock at night was'nt a waste of time after all!

I think you were imagining the dials were round he wrong way in all the confusion!

Post by: SeanyK on November 12, 2010, 06:59:15 pm
It definately wasn't a waste of time mate (ok a waste of your evening  :ashamed: ) but one things for sure, without that we'd never ever know (and you fixed the CEM cable properly & pins!) and this is bound to help countless others who run into the problem, Kufatec gave me £30 back, not great but not terrible either, covers the cost of the extra wire and whatnot needed to buy! They really should offer to make a RHD loom!
