I found a great post where Trickster posted the 91 camaro wiring i needed and now i need about the same wiring info for a 1990 IROC with TPI.


i would like to have the diagrams for the bulkhead connector on the firewall, the ones over at the ecm and the 2 clear connectors that come in with the wiring harness on the passenger side of the car. I done the TBI to TPI swap and am having a little trouble getting it going.

The Acc fuse was blowing but i believe that i have got that fixed, the injectors are from what i can tell now getting a ground to them so they will spray the fuel into the cylinder, and from what i hear my dual fans are not going to work correctly( havent gotten them in yet because i want the thing to run first). but anybody that can help me please i would greatly appreciate it.

1991 RS TBI 305 to 1990 5.7 liter TPI engine and using the 1990 wiring harness.
