hello. i assume you are referring to truck wiring, right? if this is true, to be sure, i would get a wiring schematic for your truck. it will help you to identify what pins are used for the proper accessory. you can always double check by tracing the wire back to its source. i usually rewire truck with an aftermarket harness. Speedway motors makes a great gm universal harness for under 200 beans. i tried to do the same thing in my 1971 c10 and literally watched the ignition wire, the wire with the cloth, catch fire. good luck, clark.
