Expert Reply:

Yes, for the 2022 Ford Ranger you should install the Roadmaster Brake-Lite Relay Kit, # RM-88400 along with the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit, # RM-15267; the installation instructions are linked below. Having a Ford vehicle with a "neutral tow" kit, you will default to the "B" option Instruction Sheet.

For a complete flat tow set-up, I recommend the following:

- Base Plates, Roadmaster Direct-Connect Base Plate Kit, # RM-524459-5

- Tow Bar, Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar w/ LED Lights, # RM-676 (Needed Safety Cables are included.)

- Wiring, Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit, # RM-15267 and Relay Kit, # RM-88400

- Supplemental Braking, Demco Stay-IN-Play DUO Supplemental Braking System, # DM86VR.
