Parking Sensors OPS tutorial needed

Rossimac:
Hi all,

I bought this set of parking sensors for the rear of my mk5 GTI - http://www.ebay.co.uk/itm/191211754714

I have installed the sensors but don't really know where to go with regards to wiring it up. Anyone have any good guides on this? I believe this set are from a mk6 golf and would connect to my RNS 510 in some way (via can gateway?) to enable Optical Parking i.e. radar on screen. Am I right in thinking this?

Any and all help appreciated!

SI-R32:
There should be 4 wires to connect to car

Positive,  negative

Then can high can low

Positive goes to ignition switched terminal

Negative car body

Can high low needs to goto the power train can wires,  ie on gateway or steering wheel control module or xenon hight control module,  dsg lever,  haldex unit in awd cars

Can low always has brown stripe

Can high orange and black

Plus also you'll need vcds to add it to gateway and code module etc

Ross Paul (pobmk4) on RMS is doing the wiring for mine.

Rossimac:
@SI-R32 Fantastic and cheers for the detailed write-up! I was hoping you'd see this!

I'll see if I can follow that guide when I get to the car this morning at the body shop - just had the sensors and rear bumper sprayed on Thursday. Will post any questions here later with photos to help. Will probably use the the CAN gateway as no height control module or DSG.

I've got VCDS ready to add the feature to the gateway and then code anything.


@Lyons - That's great - I'll give him a shout later if I get completely stuck. :)

Rossimac:
So after visiting the bodyshop here are the questions I have:

The cable from the sensors is coming out below my right rear light and I'll need to feed it toward the passenger door box beside the dashboard (same place as the interior fuse box, except on the passenger side), unless anyone can suggest a better position?

I can fit the ground.
The positive cable can go into my ignition switch terminal easily.

The high can and low can cables are the bits I think I'm going to have trouble with. I want to remove the pins from the gateway and put them into the sensors' loom and put the loom's cables back into the gateway. Much like this picture from a forum:



Is this the best approach? My uncle is a mechanic and suggests just splicing into the gateway's cables as there is very limited access via the cubby hole above the accelerator to start removing terminal pins.

Another relative who is a retired VW mechanic says splicing is a bad idea and could lead to the CAN throwing errors. He says the best approach is the above picture, but would need a terminal release tool to get the current cables out of the gateway, which I don't have.

Any opinions on how to get better access to the gateway or do I have to remove the dash to do this?
Is the steering wheel control module better to work with than the Can gateway to get to the power train can wires?

Sorry for the long ass post, but would just love to get this done soon as now my numberplate lights are out until I get this wired up  :smiley:
