Tekonsha Accessories and Parts - 3015-S

Streamline the installation of your trailer brake controller with this custom adapter. Simply connect the wires of the harness to your brake controller and then plug the other end into the junction box beneath your vehicle's dash.


Features:

  • Pigtail wiring adapter eases installation of your electric trailer brake controller
  • Connector end plugs into the built-in port beneath the dash of your vehicle
  • Wire end connects to the wires on your brake controller with the included butt connectors
    • Compatible with time-delayed and proportional brake controllers from TrailerMate, Draw-Tite, and Tekonsha
  • Limited 1-year warranty


Installation of Tekonsha Brake Controller Adapter

To install your electric brake controller, you need to connect the wiring of the controller to your vehicle. Certain auto manufacturers offer pre-wired options, typically known as tow packages, wherein wiring is run for you from the dash to the trailer connector on the back of your vehicle. When this is done, a port is installed at your dash so that you can easily plug in a brake controller.


Installation 1Installation 2

This adapter plugs into the port that is built into the electric junction box beneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.


To hook this adapter up to your trailer brake controller, just connect the 4 wires of the harness - ground, power, brake switch, and brake power - to the corresponding wires on the brake controller. If your brake controller came with a plug built into its wiring harness, you will have to cut off the plug and connect to the wires themselves.

  • If your 2003 Chevrolet Silverado 2500 HD has the factory installed hitch and a 7-Way connector, then all of the wires for the brake controller have been run. The factory brake controller port is located in the black box underneath the dash on the drivers side, to the left of the brake pedal. Usually a brake control adapter will be included in the junction box. If an adapter is not in the junction box you can use the Draw-Tite Universal Brake Control Wiring Adapter, part # 3015-S, for...

  • Brake Controller Wiring for a 2006 Chevy Silverado Pickup
  • If your 2006 Chevrolet has the factory installed 7-way you will need an adapter to install the brake controller. The Tekonsha Voyager brake controller has the wires hard wired into the unit so the Tekonsha Wire Replacement for GM Vehicles, 2003 - 2006, part # 3015-p, would not be the easiest way to install the Voyager. An easier route would be to purchase the Universal Brake Control Wiring Adapter 2003 - 06 Chevrolet, GMC, Cadillac, part # 3015-S, and then wire it to the Voyager brake controller...

  • Both the # 3015-P and the part # 3015-S will work just fine with your vehicle. The difference is that the # 3015-P will plug directly into the back of the P-3 controller, while the 3015-S would need to be spliced into the bare leads that exit the rear of the controller. The adapter would plug into the junction box under the dash, like you saw in the video. The controller must be mounted within driver reach, and according to the manufacturer recommendations.

Your 2006 Silverado has a port in a junction box under the dash for a brake control wiring harness like part # 3015-S. There is a possibility that the harness you have is wired differently, similar to wiring harness # 3025-S. The difference...

Since the Tekonsha Voyager does not have the plug on the back, you can use part # 3015-S. One end has a plug for your vehicle and the other end has loose wires for you to splice into the Voyager.
