I have installed the ZCI trailer wiring kit on my tesla Model 3. Follow all instructions. However, running lights on trailer on all the time, even when the car is off. And when the brake pedal is depressed the tail lights on the trailer go out! I've tried disconnecting the tail light sensor and reinstalling via the computer, and the problem continues. Not sure what to try next. Will you help?
