Ok so I have an 84 El Camino with a ratchet shifter and have put in a dash steering column and other misc parts from a 78 Cutlass salon which was a standard car, I'm trying to hook up the old reverse light wires from the Cutlass wiring harness to my B&M ratchet shifter my best guess to what is the correct plug is one with two wires one green and one blue I was told from the previous owner that the old reverse switch was plugged directly into the standard transmission and was wondering if that is the green and blue wires I'm looking at and if not what wires should I be looking for attached is a photo of the whipped that goes from the plug under the dash threw the fire wall
