I'm wiring up my motor swap project and it's been years since I figured this all out for the Chevette. I forgot how it was wired up and I'm reaching a dead end in my googling so I'm hoping you guys can help.
I'm trying to figure out what pin 110 and 108 are. I'm pretty sure I run 102 to switched 12v and 13 to constant 12v, I completely forget what 108 and 110 got wired to in the Chevette.
Edited to add: Discovered Pin 2 on my MPI relay and Pin 10 on the MPI relay were cut and have non-factory wire connectors on them in this harness. Where should these wires go in the factory configuration? The best answer I found is that Pin 10 gets constant 12v power and Pin 2 triggers the fuel pump. I'm not sure if Pin 2 should go to the rewire relay or what though.
