Have a 2013 sv w/o led mirrors and did swap to led mirrors. harness was PnP for mirror positioning. But 2 wires from car harness are not connected. I have 7 wire from car harness. Mirror harness has 4 extra wires not connected. Car harness has 2 wires not connected, a black wire and orange wire, but no voltage on either when multimeter them. Car Full on, ac on, headlights on, blinkers on??? Nothing gives voltage. Dont see any fuses blown. Anyone figure this out or have a diagram on what the factory mirror harness color codes indicate?
