updated the loom X2 and X3 connector for X31 ecu plug
 
Thanks to Mike for his excellent compiled wiring diagram PDF

I seem to have misplaced part of my x31 ecu plug loom, but took some pictures b6d (starter motor, alternator, main chassis earth, knock sensor)

Do you need any photos of the X31 loom or any of the plugs? Mine is in a box upstairs at the moment.

Yes please they are a real pain to photo on the car in situ Need to confirm colour of x2 x3 plugs

OK no problem, will get some photos at the weekend. PM me an email address and I will send them over.

Zip file with several photos and a list of the wiring colours on the X2 and X3 plugs sent.

ecu plug details

I see the ecu pictures have gone, thats helpful

The 3rd ecu is just my spare with the K6X label
