|
|
Have question for those really familiar with trailer light wiring. I have a 7 pin plug on truck. Tested pins and starting from bottom and going clockwise pin 1 is blank, pin 2 is left turn, pin 3 is blank, pin 4 is head and tail lights, pins 5 and 6 are blank. When I turn on the truck pin 4 is energized and also is energized when I turn on the headlights. So when I hook up to the boat everything works properly, but when I hook up to the rv i have no taillights. Did the same test on the rv plug and the results where the same as with the trucks but the trailer tail lights do not come on when I turn on the key or when I turn on the headlights. Any ideas? |
