Question:

I am wanting to purchase your Hopkins Custom Tail Light Wiring Kit for Towed Vehicles, Item #HM56009 for my 2015 Ford F150. I am planning on also installing a supplemental braking system air force 1 which independently operates the towed vehicles brake lights. As such, can you confirm if I need to install your separate relay kit RM-88400 my application or will it not be needed?

Expert Reply:

Yes, you are going to also need the Roadmaster Brake-Lite Relay Kit for Towed Vehicles # RM-88400 as well when you install the Demco Air Force One Supplemental Braking System for Motor Homes with Air Brakes # SM99243 on your 2015 Ford F-150.

Along with the wiring harness # HM56009 you're also going to need the Roadmaster Battery Charge Line Kit # RM-156-25.

If you're needing a complete flat towing setup, you're also going to need:

-A base plate kit, like the Roadmaster Direct-Connect Base Plate Kit # RM-524431-5,

&

-A set of tow bars, like the Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar w/ LED Lights # RM-676.
