Wiring Diagram/Schematics

If I were you, I would pull the lens covers off of the rear lights identify those wires they’re going to the lights and the brakes and maybe the clearest lights as well. Also examine the wires at the brakes see what color they are. Maybe go from there. Like I said above I don’t believe there any schematics either. If you know how to use the meter you might be able to roam some of the wires out and find out which goes to which you can’t identify them by the color on the other end. You also might get someone to assist you. You may call me if you wish.

Siri didn’t get this quite right but if you call me I can explain it.
