Roadmaster Tow Bar Braking Systems - RM77RR

  • 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.


Features:

  • 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


Specs:

  • 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.

  • Where is the Stop Light Switch Wire on a 2023 Jeep Grand Cherokee L
    I do have an option for you but there isn't a traditional stop light switch circuit on a 2023 Jeep Grand Cherokee L. Therefore, if you want to use a wired trailer brake controller you'd need a stop light switch like the RoadMaster Stop Light Switch Kit part # RM77RR. The other option would be a wireless trailer brake controller like the Curt Echo Wireless Brake Controller part # C51180 which does not require a stop light switch connection.

  • Does A 2024 Jeep Grand Cherokee 4xe Trailhawk Have A Plug-In Brake Controller Port
    There currently aren't any listings showing the 4xe models having a tow package that includes a plug-in port for a brake controller so at this time the only available option would be a splice-in wire harness. For a 2024 Jeep Grand Cherokee 4xe I still recommend the Redarc Tow-Pro Liberty Brake Controller # RED24FR along with the Universal Wiring Harness # RED69FR because it has the smallest footprint on the market for more mounting versatility and a cleaner, factory look. The wire harness...

  • Recommended Brake Controller For A 2022 Jeep Grand Cherokee Trailhawk 4xe
    As far as I can confirm there is not a plug-in port available for a 2022 Jeep Grand Cherokee 4xe. You can try reaching out to Jeep/Mopar but I can't find anything from them stating that there is a plug-in option so you'll have to go with a splice in option. For this I recommend the Redarc Tow-Pro Liberty Brake Controller # RED24FR along with the Universal Wiring Harness # RED69FR. This brake controller has the smallest footprint on the market for more mounting versatility and a cleaner,...

  • Tow Bar Wiring Kit Needed For Flat Towing A 2023 Jeep Grand Cherokee Summit
    The brake light switch wire for your 2023 Jeep Grand Cherokee Summit isn't useable so you wouldn't be able to install a brake light relay kit any way. In cases like this the turn signal will override the brake signal until the computer inside the Jeep "goes to sleep" after about 20 minutes. The general guideline is to just get all hooked up and running and let it idle for 20 minutes but gas isn't cheap so most people just take off and let it go to sleep while already towing. Since you...

  • What Powers The Diodes In A Diode Wiring Kit
    The diode wiring isn't going to be wired in series so you won't have to worry about the voltage increasing. It will only be powered by the 7-way of your motorhome when the brakes or the turn signals are activated on the motorhome. I've attached a video below where Ryan will walk you through the installation of your diode wiring. Since your 2022 Jeep Grand Cherokee has combined wiring and an unusable brake light switch wire you'll need the Roadmaster Stop Light Switch Kit # RM-751449 (WK...

    Hey Michael, The Falcon 5250 has direct-connect attachment points that hook onto a crossbar, if you remove the crossbar adapter then you'll be able to go with a direct-connect baseplate like the # RM77ZR (models with tow hooks) or # RM76RR (models without tow hooks).

  • Complete Flat Towing Setup for a 2023 Jeep Grand Cherokee Overland W/ Tow Hooks
    I would personally go with Roadmaster's stuff. They've had a really good track record in my experience and have been an industry favorite for a while.
