For the factory 7 pin wiring harnes, the brake controller wire is located behind the left (drivers side) kick panel by the floor panel. It has a small white tag labeled "brake". You may have to fish around a little bit to locate it, but it is there.
If it had the factory wiring at the bumper it will have plugs under the driver side of the dash for the factory style in dash brake controller.If it had the factory wiring at the bumper it will have plugs under the driver side of the dash for the factory style in dash brake controller.
When one is using a trailer on their car, an electric brake controller measures the car's braking speed and adjusts the electric braking power of the trailer to correspond. This helps avoid collision between trailer and car.
You should see either a brake controller box under the dashboard, or a wiring harness under or through the back bumper for hooking power from the van to the trailer.
I found it easier to use the wires to the tail lights on the tractor.
