I bought a 1980 zx parts car to get the FI off of for my 72. I got all the hardware off the car except the wiring harness. Theres a bunch of wires that go over to the passenger fender, up to some sort of box, and then continue into the fender. I believe these wires run under the dash somewhere. The question is, what exactly do i need on the harness? Im thinking about cutting all the wires except the sensors and injectors. What else would i need?
