    I am trying to install an amp in my 99 expedition. I have 5 wires to work with, black-orange, green-purple, red-black, black-green, and light green-black. I have listed below what I have on each and what I beleive they may be. Please let me know if I am even close on this. Don't want to burn something up.Thanks!

    Black-orange= audio (-) 4.97vdc this wire and the red-black are in a foil sheid with a bare steel color wire.

    red-black= audio (+).077vdc

    green-purple= 7.31vdc No clue? Help!

    light green-black= 12vdc

    black-green= grd

    I agree, that's why I'm lost, but I have it in front of me and the gray plug going into the amp has those 5 wires. I thought the red-black and orange-black were the + and - audio, but would it have 4.97vdc on the positive side of audio input?
