How To Install Roadmaster Diode Wiring Harness On 2022 Ford Ranger


My 2022 Ford Ranger has T20 Halogen bulbs, and is not wired like any of your diagrams. Per your recommendation, we have ITEM # RM-15247. What should we have received, instead? If there is a way to make this kit work, what diagram would be appropriate?

The Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit part # RM-15267 is what I recommend for a 2022 Ford Ranger. This is a universal kit that works very well and comes with a coiled umbilical for easy hook-up and wire management. I don't have specific instructions yet for the 2022 model but we have successfully installed this kit on a 2021 model which should be the same if not similar. I have attached a video of this install below for your review. The circuits you'll be teeing into on the vehicle are the brake lights and running lights.

The Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit will also allow you to add a Roadmaster Battery Charge Line Kit for Towed Vehicles part # RM-156-25 which is a great idea to make sure you don't arrive at your destination with a dead battery. I have attached an install video on this part as well.
