Gti MAF connector wires
« on: June 08, 2018, 11:23:55 PM »
Im down to the last engine connnector to solve before changing my engine 9 July.

I just paid quite a bit for the MAF connector from VW.....1k0971337 which costed me $140 AUD

Anyways........this connector comes with the 3 wires on pin 1 -3. The colours in order from pin 1 are white/yellow, green/yellow, black

Looking at the vw diagrams they all shows 4 wires with none matching these colours

Further to this when I look at pics on pelican parts site, the mk5 gti has colours yellow(cant see another colour with it), brown(I think with grey), black and blue

Looking at a photo of a friend's gti her golf had black and white on pin 3 and br on pin 2 and yellow on 1

Can anyone maybe help me figure this out so I can get the 3 wires connected to the correct locations on ECU etc?

I think 1 is voltage, 1 earth, and then 1 to ECU?

Mine, a 2007 BPY, only has three wires...I can check which goes where.

OK, mine match your picture;
1-yellow
2-brown
3-black/blue stripe
4&5-empty

Great thanks. Any way you can trace them to pins on the ECU?
Mine will be connected to a BWA engine and ECU but cant think that the pin location will be different on the ECU.

Not me...I wouldn't attempt tracing, sorry.
I hate electrical  :sick:
I couldn't even find a wiring diagram last night. You can give this a search if you like; https://workshop-manuals.com/volkswagen/gti/l4-2.0l_turbo_(bpy)/powertrain_management/computers_and_control_systems/air_flow_meter/sensor/component_information/technical_service_bulletins/page_5084/

Lol.
Thanks for the link, it looks like 2 is ground and 3 is 12v (15A feed) and then 1 should be signal to ECU.

For pin 1 it states:

ECM) J623 electrical harness connector T94 terminal 22.

Maybe someone can confirm this is the same for the BWA engine?

On golfgtiforum.co.uk it says:

BPY is the North American variant [with different emissions gubbins] of the European AAX or BWA variants

So I assume the it will be the same.

I would also assume they are similar electrically. There are a few mechanical differences, but not likely with where the MAF connects.

Have you got VCDS or OBD11?  Do you get a reading on the MAF channel?   If your MAF is the same 06F906461A part number as European/US MAFs, then the wiring should be the same.  My 2007 UK model is the same as ROH ECHTs.

VCDS. Im swapping my BLX cylinderhead with obe from a BWA in July where I will replace manifolds, wiring and ECU.
Will only know then when I try to wire in the MAF as the wirjng is not part of the engine wiring harness going to injectors, turbo etc.
BLX doesnt have MAF only temp sensor on airbox so this is why this thread started.
