    Hey guys I am starting to wire up the new flat bed with taillights and runners, every wiring diagram I find the wire colors don't match up. I have the harness off of the truck and the taillight wire colors i have are - white - green - black - brown. if it helps they were the taillights with circuit boards. I am reasonably sure the green wire is backup lights but that could be wrong. The new lights have four wires going to them so any help with what color does what would be greatly appreciated.

    what you could do is turn on parking,,,ck for pwr at the wires
    left blinker, right blinker etc and ck for pwr at the wires
