Great website ans info.
Have extra connectors/terminals and want to make up a bench harness for the GM E38 ECM and T42 TCM.
Does anybody have a schematic?
Thanks,
Mike

Thank you for the schematic!
Have some questions:
1) What does V1 and V2 columns represent?
2) E38 controller pin #13 should be pin #73 - ground. Typo?
3) T42 controller why use pin #11 accessory wake up serial data?
Pin #11 is used when key is placed into the accessory position.
Why use it when you have 12v switched at pin #31 already?
Thank you for your help.
Mike

you probably miss the Can+ and Can- pins in your OBD2 connector
Cavity 2: Class 2 serial data (purple wire)
Cavity 4,5: ground (black)
Cavity 6: CAN+ (tan/blk)
Cavity 14: CAN- (tan)
Cavity 16: battery (orange)

I have one I bought from Speartech. I can post up info from that if you haven't handled it yet.
