So I've pulled out the old EFI wiring harness to test fit and sure enough, its gonna need some work. Looks like some hack jobs have happened along the way and for the life of me, i cant figure out why its got a weird speed sensor plug at the gearbox end. But more importantly, i'm totally lost about two of the plugs. Can any 304 EFI gurus identify these plugs and what they're for?
