You need 60 feet of 10 gauge wire in two colours. Blue and black preferred.

Two automotive 30 amp breakers.

Auto motive crimp connectors for 10 gauge wire to:

  • Connect from positive battery terminal or equivalent under hood battery supply
  • Connect to and from breakers
  • connect to brake control wires under dash
  • tap into brake light switch
  • connect to a good ground

Screws to attach breakers to fender or equivalent under hood power supply

Run 1 black lead from battery supply to breakers.

From breakers run 1 blue and one black to under dash.

Black wire continues though car to rear bumper plug. This connects inside 7 way plug to Black or battery connection.

Blue wire connects to battery wire on brake control. Then also connects to brake output wire on the controller then runs with black to back bumper. It connects to blue or brake connection.

The brake control will need to be grounded to a good ground under dash.

The brake control will have a wire that will need to be connected to the wire that feeds the brake light bulbs at the brake light switch. Use a Meter to figure out what one it is. A test light may burn out something expensive.

Finally the 7 way plug on the back must be connected to ground (white or ground terminal) to ground with a 10 gauge wire.

I would recommend for signal lights etc on the trailer you get a "HOPPY" or other "tap" kit to patch into the taillight wiring.

I, as a guy that does this regularly, can do the whole thing in 3 hrs or so.

First timer allow 8 hrs.
