Wiring Harness from Performance Systems Integration PSI
We do not support the E40 ECM as it was only used for 2 years. For our E40 customers, we can provide a harness that uses a 411 RED/BLUE pcm with a tac module and pedal. We can set it up for the 4L80E transmission as well. Please PM or give us a call at 732-691-6531 to discuss specifics.

As for needing a business license, tax ID, and a buy in to place an order from them that is not true.
Convoluted tubing or not, looks to me like PSi is the better value for the dollar...
T,

Del City is another source for that stocks most of the same stuff as Waytek.
TomM, I'm with you here:
"600 bucks for a harness with no fuse block or fuel pump relay....and I didn't see a provision for the 13 pin auto trans connector.........nice stuff, but I don't think so....
Convoluted tubing or not, looks to me like PSi is the better value for the dollar..."
About $100 bucks less and PSI's is pretty much plug & play, can't beat that!

If you also look at the options they have options for the 4l60e but can do any other automatic trans as well.
Here are the options that have drop down menus that you choose according to your setup.
What Chassis?:
What Injectors?:
What Motor?:
What Transmission?:
Which ECM/ECU will you be using?:
Which Harness Model?:
