Problem: I upgraded to LED tail lights (not replacement bulbs, but all new boards and bulbs from DMC). My car has a cruise control from the mid 80's that worked fine until the replacement of the tail lights. Now it doesn't work. Also, the tail light stop bulbs (2 in each tail light) glow dimly now when the cruise is hooked to the stop light wires (green/purple wires). I can unplug these connections and this goes away. Cruise does not work with new LEDs.
What I know: I switched back to my old incandescent board on one side and the cruise now works and no more dimly lit LED on the other tail light. I need a resistor that behaves like the old incandescent stop bulbs and only need this on one side.
What I need to know:
1. What is the total resistance of the 2 stop light incandescent bulbs? Despite watching several YouTube videos, I cannot figure out how to measure ohms. What size resistor do I need?
2. How do I properly install a resistor? I think I have to splice it in across the ground and positive... What color wires do I splice in to?
Thanks for any advice,
Andy
