So I'm doing a COP conversion on my Vortec 350, and need the wiring for the coils. I have the 2 short coil harnesses that go from the coil to the large white plug on each side. But, I need the engine harness side of the large white plugs, and their corresponding wiring. Is there any better way to get that than buying an entire Gen III harness and gutting what I need out of it?
