How to Add a 7-Way Connector to a 2019 Honda Passport

Question:

Will this 7 pin connector function with an adapter for a 4 pin trailer connection? It appears that the wire pin placement differs from the standard 7 pin connection with the ground wire at the 3 o’clock position where the right turn green wire would be. Does it require a “special” adapter for 7 to a 4 pin trailer connection?

I would be happy to help you set your 2019 Honda Passport up with a functional 7-way connector. The Tekonsha T-One Vehicle Wiring Harness for Factory Tow Package item # 118291 you were referencing will not work with an existing 4-way connector or function as designed by splicing it in. This adapter plugs into your vehicle's factory tow package wiring harness. The converter plugs into the factory wiring harness in your rear cargo area, on the driver's side. This adapter only works if you have the tow package.

If your Honda Passport doesn't have the tow package and/or only has a 4-way connector you will need the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires item # ETBC7. The kit includes a pre-wired 7- and 4-way trailer connector that mounts easily at the rear of your Passport with an included bracket. This kit is designed for use on a vehicle with an existing 4-way flat trailer connector and plugs directly into it. These two parts are the only way you can add a fully functional 7-way connector to your Honda Passport.

If you need a brake controller I recommend the Tekonsha Prodigy P3 Trailer Brake Controller item # 90195. This is a proportional brake controller that activates your trailer brakes in proportion to your Passport's braking action. It automatically adjusts the trailer's braking based on deceleration of your vehicle.
