2004 Chevrolet Avalanche - Tekonsha Custom Wiring Adapter for Trailer Brake Controllers - Pigtail - GM

  • Brake Controller
  • Wiring Adapter
  • Tekonsha
  • Wired to Brake Controller
  • Vehicle Specific

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 '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.

  • Brake Controller Does Not Work After Installation on a 2005 Chevy Silverado
    On certain year Chevy trucks there are additional connections that need to be made under the hood to make everything fully functional. I have included a link to an FAQ article to help you. Make sure that you are plugging in the harness into the spot on the top row, second from the left. The Curt harness you should be using is # C51352.

  • Amperage Capacity for Power Wire on a Factory 7 Way on a 2009 Chevy Suburban
    Typically, the power wire on a factory 7 way is on a 40amp circuit with a fuse or breaker somewhere near the fuse block. Sometimes it can be a 30amp circuit. If you are going to be running more than 30amps, I would call the service department at the dealer you got it from and find out for sure. You could also give the fuse block a quick check to see if it is clearly identified.

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.
