Question:

Hi, I asked way back when for this complete parts breakout for Roadmaster and a 2021 Ford F150 - I now have a 2025 Ford F150 and I want a new parts breakout for the brake/taillights, smart diodes but not tow plate or nighthawk. Can you do taht for me please?

Hey Bob, welcome back and congrats on the new truck!

To flat tow your 2025 Ford F-150 you'll need the following parts:

Base Plate Kit - Roadmaster Direct-Connect Base Plate Kit - Removable Arms item # RM45EQ

Wiring Harness - Roadmaster Universal Hy-Power Diode Wiring Kit item # RM-152 or item # RO44FR if you have LED lights on your F-150. You may also need item # RM-910030-5 and item # RM-910030-7 if you didn't keep the connector off your old truck.

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

Brake Light Switch - Roadmaster Brake-Lite Relay Kit for Towed Vehicles item # RM-88400

Supplemental Braking System - Roadmaster InvisiBrake Supplemental Braking System item # RM-8700

What parts did you keep from your 2021 F-150 flat tow set up?

Hi, what does the Roadmaster BrakeMaster Custom Fit Seat Adapter Part Number: RM-88316 do if using the Invisibrake system? My current install on my 2021 Ford F150 uses a pully behind the brake with a cable attached from Invisibrake around the pully to the brake. Thanks - Bob

@RobertR You can disregard that information. You don't need the item # RM-88316 with your current system. It works with the other Roadmaster braking system item # RM-9160.

I understand the braking system in my 2025 Ford F150 is electric based, are there any other supplemental braking systems that can be removed and are not permanently fixed? Thanks

@RobertR There sure is. The Blue Ox Patriot Portable Flat Tow Brake System item # BLU37TR is going to work with your 2025 F-150's brakes. It's compatible with all models and the adjustable or non-adjustable pedals.
