Here's where we're at trying to solve the headlights not working issue. I tested the headlight bulb as well as the high beam bulb and both work. But, still can't get the headlights to turn on. I temporarily wired the LED courtesy strip to the red and gray dash wires. The instructions indicate that turning the headlight switch full counter clockwise will illuminate the courtesy light. As soon as I connected the test battery, the courtesy lights lit up but would not turn off with the headlight switch. That, and the headlights not working makes me wonder whether I have a defective headlight switch. So...ordered a new one.
