Question:
I have a 2024 Ford F150 801A Raptor what do I need for my tail lights to work correctly. There is no external brake light switch under the dash, I believe it is within the abs/brake master cylinder assembly.

Hi Terry; I'm not sure what the exact location of the brake light switch is but we do know that it is unusable on the 2024 F-150 Raptor. What you will need to do is install the Roadmaster Stop Light Switch Kit # RM42MR. If you don't already have a wiring kit so you can use your tail lights while flat towing you need the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267. You will also want a charge line kit # RM-156-25.
I see you also looked at some supplemental braking systems. If you don't already have a brake system and your RV has air brakes then the Demco Air Force One # SM99243 you looked at is what I would recommend. Otherwise, I recommend the Demco Stay-IN-Play Duo # SM99251. Both require the Roadmaster Brake-Lite Relay Kit for Towed Vehicles # RM-88400 for installation.

Hey Terry, how did things go getting the tail lights on your Raptor working with the Roadmaster kits? Your update could make it easier for others setting up a similar flat tow system.
