Tekonsha trailer brake controller harnesses exist to make connecting your brake controller to your vehicle as easy as possible. These custom two-plug units are specifically designed to be used with any Tekonsha brake controller. The Plug & Play feature on the Tekonsha wiring harnesses makes them easy to install. Simply plug one end of the harness into the back of your desired Tekonsha brake controller and the other end into the port in your vehicle. No cutting, splicing, or taping required. Each wiring harness is made up of four copper wires wrapped with a braided nylon thread to insulate the wires and protect them against nicks, punctures, and elevated temperatures. The four-pin Plug & Play connectors on each end of the harness are uniquely designed, with one end to fit each vehicle based on make and model year specifications, while the other end plugs easily into any Tekonsha brake controller. Tekonsha trailer brake controller harnesses are custom designed, giving you plenty of wire to reach between where it is connected to the vehicle and where it connects to the brake controller without stretching or straining the wires. And because Tekonsha is the leader in wiring and electrical, you can relax knowing your connections will be safe and secure, so you can hit the road with confidence! With Tekonsha, Life’s a Journey. Stop Often.

Fits just as it’s designed and much cheaper than ordering direct.

Lots of discussion on the internet about connecting third party trailer brake controllers to the new Ranger base model when the factory brake controller is not ordered but the towing pkg with hitch and wiring is. This cable connected directly to a factory plug under the dashboard and made the installation of the Tekonsha P2 controller straightforward. Added a diode and a circuit breaker because I didn’t know if the factory plug included them; can’t hurt and not expensive. Have not tested the automatic emergency braking component because, well, Airstreams are expensive, and I can imagine the insurance agent saying, ‘You did WHAT?’
