Im swapping an 85 gn motor into my 63 cutlas conv.
I used the stock engine harness and ecm.
My question is I have 3 wires that go back to a brake switch, torque converter which is a purple,a pink/blk from egr control and pink/blk from recovery canister. Does anyone know how they get wired? Also the diagram I have has an engine light with 2 wires going to it 1 from the ecm and 1 from reader port, Do these 2 wires go on either side of a indicator light? This is the last problem Im having. Im going to use a vss and module from Caspers. Anyone have any other ideas.
Thanks
