Install your electric brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the built-in harness beneath your vehicle's dash.
Features:
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 install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.
This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.
