Recommended Tow Bar Wiring for 2017 Ford F-150


I need a wire kit to flat tow a 2017 F-150, King Ranch 4X4. The truck has LED lights and I use a supplemental braking system. Do y’all make something for this setup?

For your 2017 Ford F-150, I recommend going with the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. This kit is confirmed to fit your truck and will wire it to accept your RV's tail, brake, and turn signal lights. The harness includes a round 6-Way connector that you will install in front of your F-150 and enough coiled wire to go from there to the RV.

I have attached an installation video on the 2016 Ford F-150 that you can use for reference.

Since you are using a supplemental braking system, you will need to add the Roadmaster Brake-Lite Relay Kit # RM-88400. This is needed to prevent the F-150's brake signal from overriding the turn signal from the RV when applying the brakes during a turn. I have attached another installation video for this kit that you can also check out.
