    Hoping to get some help with wiring info. I'm an idiot and in the process of relocating my VSC/Traction Control button, I snapped a wire. Looking to get an aftermarket switch to replace it, but I can't for the life of me find a wiring diagram to figure out which wires do what.

    I’m honestly not sure. I guess I’m mostly trying to figure out what each wire color does so I can splice them into an aftermarket harness correctly.

    I am trying to do this move also. My aftermarket momentary switch has 4 wires.
    Green from Source,
    Red 1 to accessories
    Red 2 Illumination
    Black Ground.

    Could you tell me which wires to which per the factory switch harness per the drawing below. VSC (+) goes to ??? etc.

    You need a latching switch, not a momentary type. Also a switch with independent illumination.

    GREEN to VSC
    RED 1 to ground.
    RED2 to Green Illumination
    Black to Brown Illumination

    On the latching switch type. I thought I would need momentary since that is what the factor switch seems to be, correct?

    Seems...is the clue. Only one way to be certain, test the function. Press, view lights on dash. Turn vehicle off then on again and see if the indicator on dash is still ON.
