Expert Reply:
Hey Paul! The OEM switch on your 2023 F-150 is unusable. You will need to add a RoadMaster Stop Light Switch Kit to complete the installation of your InvisiBrake # RM-8700. You can choose from the following based on your configuration:
-Non-Hybrid Model With Non-Adjustable Brake Pedals use # RM89ZR
-Non-Hybrid Model With Adjustable Brake Pedals use # RM42MR
-Hybrid Model use # RM-751000
What motorhome are you towing with and where are you headed once you get your F-150 set up?
