I made a trailer out of my old 89 Nissan pickup. It didnt have enough wires in the harness in the middle of the truck to make all the correct brake lights come on, it makes the amber turn signal lights go as brake lights (they also work OK as turn signal lights) and I cant find any wires in the main harness that make the other red high output brake lights work. Is there a way to make the actual brake lights on the Nissan work?
Do I have to follow the wires from the tail lights in the back forward to where they do whatever magic makes them work? I dont think I have much from the large round trailer plug that would make the brake lights work independently from the turns.
Edit: Forgot the mention, the trailer has a small flat squarish device in the wiring between the factory wiring harness it was tapped from and the trailer plug in the rear bumper of the old pickup, can I take power from that to my brake lights? Is the little square device the magic part that unscrambles the brakes from the turns?
