I have been looking everywhere for a diagram to build a bench top harness to read/program E38 ECM'S and cant find anything. Can someone please help me with a diagram? I also have the T42 trans controller if that makes a difference.

Awesome thank you. I forgot about looking for that in my files. Its the one I used for my LS1 bench programmer. Didn't think to look in that pdf lol. Hopefully I can work the T42 TCM into the same harness. Thanks again.
I built one and put a metripack connector in my CAN bus wires going to the TCM, if I am just bench flashing a E38, unplug the connector. T42 + E38 plug her back in, simple and good to go! TCM connectors are hard to come across from salvage. They can be pricey new.Originally Posted by woomugen
