Motor wiring swap
Hello All!
Presently undertaking a swap from a 3.1L in a '90 Firebird to a '89 GTA lined out 5.7L. We have the engine bay wiring harness, the computer, and all the sensors from the '89. Can't track down a schematic/diagram for the bulkhead connector fuse block for the '89 or the '90. I know that there is something different between the two years. Splicing or moving the wires within the harness is not a big deal, just need to find a diagram to see what needs to go where. Any help or direction of where to search would be greatly appreciated. Thanks ahead of time.
