Roadmaster Tow Bar Braking Systems - RM-751459

  • Stop Light Switch
  • Roadmaster

Avoid damage to your vehicle by ensuring that your supplemental braking system is properly positioned and working effectively. Kit activates your RV monitoring system to alert you when the brakes of your towed car are being applied.


  • Activates motorhome brake-monitoring system whenever brake pedal in towed car is applied
    • Ensures that the supplemental braking system is functioning properly
  • Works great for any application that does not have a tow position in the ignition
  • Wires directly into towed car's fuse box for constant current
  • Made in the USA


  • 12 Volts
  • Application: custom fit for your vehicle

This kit allows your RV's monitoring system to alert you whenever the brake pedal of your towed car is being applied. Other systems operate according to whether the air cylinder is extended and provide no indication of what is happening with the pedal itself. If your supplemental braking system is improperly installed, it may be continuously pressing on the pedal, impeding it from fully retracting and possibly causing damage to your vehicle's tires and braking system. With Roadmaster's Stop Light Switch Kit, you will always know when the brake is being depressed, and you will avoid costly damage.

Average Customer Rating:  5.0 out of 5 stars   (4 Customer Reviews)

Avoid damage to your vehicle by ensuring that your supplemental braking system is properly positioned and working effectively. Kit activates your RV monitoring system to alert you when the brakes of your towed car are being applied.


Kit for perfectly. A little challenging to hold bracket in place and get nuts to bolt to dash aligned and started. Helpful hint to remove obdII bracket to make it easier to bolt bracket in place, then reinstall afterward. Etrailer service was excellent to do business with!


This switch makes the braking movement turn on the light within our toad vehicle since our vehicle has a dead switch when in tow mode. So far it has been working fine just hard to see the tow display light maybe have to extend the display light to inside the coach dash.


Worked as advertised was delivered on time at a good price.


Great product, perfect fit, easy to ins tall

  • Installing the Roadmaster InvisiBrake on a 2016 Ford C-Max
    I am attaching a video of the Roadmaster InvisiBrake Supplemental Braking System # RM-8700 being installed on a 2010 Ford Flex that you can use as a reference for the installation. Due to how involved the installation process is this, along with the attached installation details is, is the most effective video I can recommend for you.

  • Installing the Stop Light Switch Kit RM-751459 On a 2016 Ford C-Max
    In regards to the Roadmaster Stop Light Switch Kit part # RM-751459 which is a requirement for the Roadmaster BrakeMaster Braking System part # RM-9100 on your 2016 Ford C-Max, there is indeed a 12 volt power wire that needs to be run through the firewall from the positive terminal on the battery or fuse box to the switch. I watched the video that you referenced and as you stated it doesn't exactly show where the wire was ran through the firewall. However, with my personal experience in...

  • Monitor Light On Stay-In-Play Duo for 2017 Ford C-Max Wont Come On in Tow Mode
    The stop light switch circuit on the 2017 Ford C-Max is not active while in tow mode so there will be no way to power the monitor light for a braking system like the Stay-In-Play Duo part # SM99251 without a stop light switch, the Roadmaster Stop Light Switch Kit part # RM-751459.

    There are a few items needed when flat-towing your C-Max. You will need safety cables like part # RM-643 and tow bar lighting like part # 154-792-118158. I have attached a link to an installation video for the wiring on a C-Max. You will need a stop light switch part # RM-751459. This ensures the brake system is functioning correctly.

  • Does Reservoir of RoadMaster BrakeAway Kit for BrakeMaster Have Specific Mounting Location
    It is definitely a smart idea to use the BrakeAway Kit # RM-8600 with your Roadmaster BrakeMaster for RVs w/ Air or Air Over Hydraulic Brakes # RM-9100 although there is not necessarily a recommended spot we can offer to install the reservoir in a 2016 Ford C-Max. We have not had a chance to install this specific part in this specific vehicle, but I took a look at the owner's manual and since the air lines do need to be two feet away from a heat source like the engine, your best bet is...

  • Setting Up 2014 Ford C Max For Flat Towing
    The Blue Ox # BX4325 Aladdin tow bar will perfectly compatible with the # BX2639 base plate you mentioned. The only reason you don't see the Aladdin mentioned is that Blue Ox no longer produces it. If you don't have the rest of the equipment lined up yet, to wire the C-Max I'd recommend the # RM-15267 diode kit from Roadmaster. For a braking system, I like the Blue Ox Patriot # BLU37TR for a portable system or if you prefer something that's permanently installed, the Roadmaster Invisibrake...

  • Parts Needed to Flat-Tow a 2015 Ford C-Max
    According to my research, your 2015 Ford C-Max is flat towable with all four wheels down but there will be certain procedures you need to follow which are listed in the owner's manual so I recommend checking these out first. In order to flat-tow a C-Max with all four wheels on the ground behind a motorhome you are going to need a tow bar, base plate kit, safety cables, tail light wiring harness, supplemental braking system, and possibly a high-low adapter. There may also be a few other...

  • Parts Needed to Flat Tow a 2014 Ford C-Max Energi Behind a Motor Home
    When a vehicle is new manufacturers do not have easy access to all models of that vehicle. If they cannot test it then they have to say items are not a fit until they can test it. Roadmaster has since tested base plates # 524432-1 on all models of the 2013 and 2014 Ford C-Max and they do fit all models included the hybrid and Energi models! Next you will need a tow bar. I recommend the Falcon 2 tow bar, # RM-520, since it is one of the most popular compatible tow bars for Ford C-Max owners....

    When you plan on flat-towing your 2014 Ford C-Max Hybrid, there are 5 things that are needed.
