So, I started to reconnect the wiring harness in my 1984 z28 h.o. and i found a plug completely pulled apart. I recently found out that a tweeker may have messed with the car before I purchased it. The plugs wiring colors are orange, black/white, red/white, and brown. at least that is how they look lol the wires go to a relay on the drivers side firewall. I have a new plug to repair it but I am unsure of the order or pin locations of the wires.
