Install your electric trailer 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 port in your vehicle.
Features:
Note: To illuminate your vehicle and trailer brake lights when you activate the manual override on your brake controller, use this adapter in conjunction with the Tekonsha brake controller converter with 7-way adapter (30235-P - sold separately). Required for use in the state of California.
This adapter plugs into the 5-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness near the emergency brake pedal.
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 cutting or splicing of wires to install. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there is no hardwiring, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.
