I did a 87 gn swap in my gta. Motor is in but I'm not sure what wires need to be used. I'm running the stock tpi harness for the starter and the alternator. ( all it does is crank the car) as for the gn harness I'm running it as a stand alone along with a fuse box made for the c100 plug. ( don't know what pins on c100 need power) in the car is the stock fbody fuse box along with the stock dash harness that runs over to the 87 gn ecu. ( some wires match on the clear connector on the ecu side, some dont) is there a thread that shows what I need to do to wire this swap up so that it can fire up. Or is there a person that has done this swap and can walk me through it. Car cracks, but won't fire up. What am I missing? I'd love to get someone with the knowledge to direct me in the right direction. Thank you.
