Anyone have experience rebuilding left control unit? My original quit providing power to the running lights. Bought a used and new unit and neither of them work to the wiring diagram. Diagram I am using shows power coming into the switch on a brown with a red tracer. It provides power to the white or dark blue to the headlight depending if on Hi or Low beam. It also provides power to the orange with white tracer and light blue with white tracer for the running lights. It turns off power to the side that is selected and provides power from the grey wire from the flasher to either the orange or the light blue causing that side to flash. All three units will flash the turn signal but not turn on the running lights.
