Where is the ecu on a 4x4 cossie i know the 2wd ones are behind the cover in the dash, also is the ecu a l8 on a 4x4 and is the engine loom on a 4x4 saph cossie the same as a 2wd, cheers.

 

Remove the glovebox by giving it a good firm pull and the ECU is behind there.

It is the bottom silver box for the engine ECU, the top one is the ABS ecu

ECU on 4x4 is indeed L8 - non cat cars are red sticker and cat cars are green sticker - exactley the same hardware, just the software that differs slightly for lambda control on latter models (green sticker).

The loom is nearly the same, but the L8 has the TPS wires the opposite way round for the outer 2 and also has a knock sensor unlike the L1 and L6

 

L8 is mounted in a frame behind the glove box lid,drop the lid and pull it towards you to remove it from the clips......you will then see the L8 and ABS ecus in the mounting frame....

4x4 engine loom is different

 

Open the glove box, and carefully remove (dont force it - she should come out easily).

Hey presto - ECU is behind!

Loom almost the same - the TPS is different on the 4x4. and the rest depends on spec (eg Knock sensor etc)

JJ

 

what is the difference in the looms ?

See my above post

 

yeah sorry missed that part, cheers

 

The TPS voltage goes the wrong way I think

And as mentioned, there's a knock sensor too.

 

also the 4wd loom connects behind the battery where the 2wd connects behine the dash

tps are different, also the water tem gauge wire is in a different place

 

I found that out when i went to replace my m8s i was like its there on my Head (mine being 2wd and did'nt know they were differnt )
