Question:

Will this work on a 2023 Ford F150 with LED tail lights?

asked by: Martin H

Expert Reply:

No, it will not. Since your 2023 Ford F-150 has LED tail lights you will need the Roadmaster Smart Diode 7-Wire to 6-Wire Wiring Kit for Variable Voltage LED Tail Lights item # RM38FR. The issue is that the brake and running lights will all be the same brightness with the standard diodes included in the Demco item # DM9523010-54. The diodes in the Roadmaster item # RM38FR kit convert the 12V signal from your RV's wiring to a 9V signal which allows the differentiating brightness needed between the tail and brake lights.

Some other parts you will need to flat tow your 2023 Ford F-150 are listed below:

Tow Bar and Safety Chains - Roadmaster Sterling Tow Bar item # RM-576 and item # RM-674

Base Plate Kit - Roadmaster Direct-Connect Base Plate Kit - Removable Arms item # RM38VR

Charge Line - Roadmaster Battery Charge Line Kit for Towed Vehicles item # RM-156-25

Supplemental Braking System - SMI Stay-IN-Play DUO Supplemental Braking System item # SM99251 or item # SM99243 if your motorhome has air brakes

High Low Adapter - The tow bar needs to be within 3" of level. If you measure the height of the inside top of the hitch receiver tube on your RV, and the height difference is more than 3 inches above/below the base plate tab height, you'll need a high/low adapter. I have linked a FAQ article that explains all this in more detail along with our selection of adapters.
