Roadmaster Tow Bar Braking Systems - RM-751490

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:

  • Application: custom fit for your vehicle
  • 12 Volts


By tapping into your towed car's brake-light switch, 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.

Video Transcript for Roadmaster Stop Light Switch Kit Review

Today we're going to be taking a look at Roadmaster's line of custom stoplight switch kits. You'll want to refer to our fit guide for the appropriate switch kit for your vehicle.Here on our motor home we have our indicator light that's connected to our stoplight switch. When this light illuminates, we know that our braking system that is installed is applying the brake pedal in our towed vehicle. And we're going to get this signal thanks to our stoplight switch. Here when I hit the brake in our motor home, the light's illuminated so I know that our braking system is working properly.This stoplight switch is going to provide you with an additional brake stop signal. This is important if you're flat towing a vehicle that doesn't have a brake signal when in tow mode.

Without a signal you'll have no way of monitoring whether or not your brake pedal is being depressed. You can use this stoplight switch to connect to the indicator that comes with your supplemental braking system so you can verify for sure that your brake pedal's being depressed when you hit the brakes in your motor home.In most instances it'll be well hidden or blend in with the rest of the wiring down below so you won't even notice it. Here you can barely even glimpse the switch itself. And the kit comes with everything you need to get it installed. This includes the switch, the wiring, the fuse and the custom bracket that's specifically made for it to mount right onto your vehicle.

The bracket's really what makes it custom for your vehicle. It allows the switch to mount seamlessly and easily adjusts to the contour of your brake pedal.A less common use is for a brake controller. If your vehicle doesn't have a compatible brake signal for your brake controller then you can install one of these and get that signal for your brake controller to easily hook up to your trailer.And that completes our look at Roadmaster's line of custom stoplight switch kits.

etrailer’s installation video was very helpful. However, the mounting bracket holes on either end seem to be the same size (the video and instructions state that the switch fits into only one end but for me it fit into both). Consequently, it is not clear which side of the bracket to use for the switch vs the vehicle stud. One other installation hint, perhaps unique to the Wrangler Rubicon or Wranglers with upgraded audio/Uconnect, there is an electronic module (3”x4”), mounted to the dash framework behind the lower dash panel, that must be dismounted in order to allow access to the bracket mounting location (see photo). 608335

  • Recommended Parts Needed to Flat Tow a Jeep Wrangler JL or JL Unlimited
  • For your Jeep Wrangler JL, I recommend starting with the Roadmaster EZ5 Base Plate Kit # RM-521450-5. This kit has removable arms to give you a very clean look when not flat towing your Jeep, and also gives you a clean connection to your tow bar when towing behind your motorhome. I recommend installing this base plate using Loctite threadlocker # LT37420 to keep your hardware from vibrating loose over time. For your tow bar, I recommend the Roadmaster Nighthawk All Terrain, Non-Binding...

  • Recommended Toad Towing System for 2018 Jeep Wrangler JL
  • Since you already have the Blue Ox baseplates # BX1139, I recommend using the Blue Ox Alpha Tow Bar # BX7365 which comes with the safety cables you need as well as the hitch pin.

Then for your tow bar wiring I recommend the Roadmaster Diode...

  • Why is the Roadmaster Stop Light Switch Kit Needed for a 2018 Jeep JL Wrangler
  • I cannot tell you the exact "influencer" as you referred to it as but while the vehicle is setup for flat-towing, the brake light switch will shut off after 10 minutes of inactivity. If you open or close the door that will then wake the vehicle up but as you will not be opening and closing the door while in tow you will need to use the Roadmaster Stop Light Switch Kit part # RM-751490 in order for a supplemental braking system to function properly on your 2018 Jeep JL Wrangler.

  • Wiring Options for a Brake Controller on a 2018 Jeep JL Wrangler Unlimited Without Tow Package

Once you have that installed there are a few options for you. You can either install the 7-Way RV Upgrade Kit # ETBC7L which only adds 12V power to the 7-Way and allows you to use the Curt Echo # C51180 brake controller with an Apple or Android smart device, or you can install the Universal Installation Kit # ETBC7...

That connection will go right to the battery. I have a video attached that shows this product being installed on the 2018 Jeep JL Wrangler Unlimited. The part about the fuse starts at...

  • Installing Roadmaster Flexo-Coil Wiring on a 2019 Jeep Wrangler Rubicon JL

From what I could find I believe that the running light should be a white and gray wire on your driver's side but a white and orange wire on the passenger side. The stop/turn signals should be found on the yellow wire for the driver's side and the...

  • Why Dont Side Marker Clearance Lights Come On When Installing Diode Tow Bar Light Kit on Vehicle
  • You did everything correctly and the Roadmaster Diode Kit part # RM-15267 that you referenced is working properly. So diodes are designed by nature to prevent current from backfeeding onto the rest of the vehicle's wiring. So when you installed the diode intended for application of the running light circuit right near the taillight assemblies it is allowing current to go just to the taillights of the vehicle and not further back to illuminate any of the side marker lights.
