Hi all I just picked up a kit car with a L67 from as SSEI SC. I have the original engine, trans, PCM wiring harness fuse boxes, etc. I am trying to wire up the engine bulkhead to get the engine started. Does anyone know the bulkhead pins, what needs grounded, constant power, ignition power. I have the purple starter relay wire isolated and I the OBD2 port wires. I've tried to find standalone harness directions, not much detailed info on using the original to create a standalone.
