Trailer Brake Lights Not Working 7 Pin. The question is if I cut the wires at the hitch side will. Electric brakes on any trailer is not a bad thing.
The thing is I have to go to the tail lights to make attachments. Running lines and trailer brakes work, but brake lights and turn signals do not. If battery voltage is not available athe trailer connector, check the CHMSL fuse.
Sometimes they slip out and touch together.
I even have all lights on the ZJ - only thing is that the brake lights won't work on the trailer.
Running lamps are good, as is my brake controler. But nothing happens when I press the brakes. It's because larger trailers will occasionally have a separate circuit for running.
