Does anyone have a diagram of the dash harness that goes through the firewall?
We're still fighting with this 2.3t swap in a 92coupe. The wire thats suppose to start the car with the key does not.

 

Does the starter work? Or problem with ignition?

Hey did you ever respolve this? It sounds exactly like what is happening to me-

Car starts, then dies right out. I was told I needed to swap in a 5.0 dash harness, but I have read that they are the same (I have a 93 dash harness from the 2.3l, and 93 engine, efi, o2 harnesses, with a 92 computer).

Thanks!
