Boutht a used trailer to haul my Austin Healey to various shows etc. It came with a controller that is to be mounted in the tow vehicle (A 1997 Jeep Cherokee). There are 4 wires coming out of the controller, red, blue, white, black. I installed a trailer hitch and the associated connector on the jeep. The connector has the usual leads to operate the lights, they all work okay. There are also three extra wires for the brakes, I assume. A red, blue and white wire. I tested the brakes on the trailer by using a spare battery, they work fine. Now the question, how do I connect the controller in the jeep, to the wires on the connector? I have the white wire going to chassis ground both on the connector at the rear of the jeep, and from the connector. I also have the red wire (from the controller)going to the car battery, and back to the trailer connector (red wire). The blue wire from the controller goes to the brake switch and also back to the connectors blue wire. The problem is when I connect to the trailer the brakes lock up. When I remove the red wire, they release.
Very confusing.
