Does 2021 Ford F-150 with BrakeMaster Require Relay
Question:
Am setting up my 2021 Ford F-150, XLT, to tow behind motorhome. I am using the Blue Ox base plate, and will be wiring with the Roadmaster wiring kit RM 154. I plan on using my Roadmaster Brakemaster 9160 for the supplemental braking system. The motorhome is already set up with the air line and brake monitor wiring. Do i need a brake relay switch and if so what do you recommend ? Thanks

Expert Reply:
Since you have the Roadmaster BrakeMaster # RM-9160 installed on your motorhome what you'd need to finish the install on your new vehicle is the Roadmaster Second Vehicle Kit part # RM-98160.
Since you are doing a diode kit for wiring and the BrakeMaster presses the brake pedal you will need the relay kit as well part # RM-88400.
