Wiring a Brake Controller on a 1999 Chevrolet Suburban

Expert Reply:

Your 1999 Chevrolet Suburban does not have a port under the dash to connect a brake controller harness. You will need to hardwire the Prodigy controller, item # 90185, with brake controller 7 and 4-way installation kit, item # ETBC7, or a 6 and 4-way installation kit, item # ETBC6, depending on the connector you need for your trailer. These kits come with everything needed to install the brake controller and wiring from scratch as long as you have a 4-way connector installed on your Suburban.

If you do not have a 4-Way connector installed then you will need the custom fit T-One Vehicle Wiring Harness with 4 Pole Trailer Connector, item # 118319, to install the 4-Way connector in the factory connector.

If you already have a six or seven way connector installed on the Suburban then you will just need to wire the brake controller output wire, blue, to the trailer connector, the black wire to 12 volt power, the red wire to the brake switch output wire, and the white wire to ground.
