Roadmaster Tow Bar Braking Systems - RM-751452

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


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.

This product was exactly what I needed. I wanted an indicator light that told me when the brake pedal moved on my towed vehicle, not when my brake system was activated. This part fit perfectly on my 2014 Jeep Wrangler sport. Others with newer wranglers reported having to notch bracket but there was no need for that on a 2014. I wired mine a little differently than the instructions show and there was no need to tap into the wiring on my Jeep. My indicator light recieved constant power from my coach, when the brake is pushed it completes the circuit with a ground from the coach and the light comes on. I feel confident that if there is a problem and my brakes are activated when they shouldn’t be I will be aware of this before it causes damage to the toad brakes. Great product 494987

There was a challenge presented when installing the Roadmaster Stop Light Switch (Kit #751452) on my 2015 Jeep Wrangler Sport Unlimited. The kit's Black C Bracket was not able to swing around fully to allow the kit's gray stop switch to be in line with the brake pedal. This was due to blockage caused by existing jeep's stop switch gray mounting bracket. As a result, I had to cut a notch using a Dremel and a grinding bit. The area where I had the interference from the jeep's bracket and the notch to allow proper installation is indicated in the attached photo. It is imperative that the kit's stop light switch when mounted correctly is fully depressed. If not, 12 volts will be sent to the Evenbrake's transmitter which will result in an alarm and failure to use the Evenbrake system. Also in reference to the Roadmaster installation instructions, there is no removable lower plastic cover. Installation requires twisting ones body under the dashboard with limited use of my left arm (I am right handed) to use tools. I ordered the stop switch from etrailer.com. I am using a Roadmaster Evenbrake system. I do want to state a clarification concerning the battery based on what I read in etrailer's and other forums. You do not have to disconnect the jeep battery on the 2015 Wrangler Sport Unlimited Model. Jeep made a change in the second edition of the 2014 operators manual which is reflected in the 2015 manual. The earlier 2014 edition did state the disconnecting of the battery before towing. I had informed the Roadmaster tech department of this change. The 2015 Jeep Wrangler Sport Unlimited steering column does not lock. You do not have to leave the key in ignition. You can remove it when ready to tow. My 2015 jeep has the power convenience group. The vehicle has two 12 volt convenience outlets. One is only powered on when the ignition switch is on. The other outlet is connected directly to the battery via a fuse. It is on all the time. This is the outlet I use for the Evenbrake. Now, Jeep does state not to plug in devices that use more than 13 amps or 160 watts. Roadmaster as per their installation manual indicates that the maximum draw of the Evenbrake is 10.8 amps. I reviewed all the above to the Roadmaster tech department and they said I should not have a problem using the Jeep's always on 12 volt outlet. We recently went on a camping trip on Columbus Day weekend to a campground 120 miles from the house and no power problems were encountered with the Evenbrake system. One other clarification is that the Jeep's brake lights are tied into the power convenience/electronics system. The brake lights will operate for a short period of time after the ignition is turned off and/or you open the jeep's door. Use of the brake lights will time out. This is the primary reason why I chose the stop light switch bracket kit. The Roadmaster Evenbrake transmitter and the hot leg to the kit's stop light switch are fed from a dedicated 10 amp fuse protected line from the battery. This way, I avoided drilling a hole into the weather resistant under the hood fuse box plus negating the need to make rube goldberg connections to existing fuses. 155854

Thanks to a review I was aware I might have to grind out part of bracket to get it to fit. I did have to. Roadmaster said it wasn't necessary . I think they have to update the bracket for the newer models. Etrailer was more helpful than Roadmaster. 165406

Ask the Experts about this Roadmaster Tow Bar Braking Systems
Do you have a question about this Tow Bar Braking System?


  • What do I Need to Flat Tow a Jeep Wrangler JK with Factory Bumper
  • To flat tow your Jeep Wrangler JK behind your motorhome, you will need a base plate kit, tow bar, safety cables, tail light wiring harness, and a supplemental braking system. Depending on the year of your Wrangler, you may also need a Brake-Lite Relay, # RM-88400, (2012, 2013, 2015-2018) or a Stoplight Switch, # RM-751452 (2007-2011, 2014). For your base plates and tow bar, I recommend using the Roadmaster Direct Connect Base Plate Kit, # RM-521448-5 for 2010-2018 or # 1429-3 for 2007-2009,...

  • Recommended Wiring to Flat Tow a 2014 Jeep Wrangler 2-Door with 2005 Bounder
  • I'm glad no one was hurt in the loss of your Liberty's brave fit against the cement truck, but don't worry, I can help you equip your Wrangler with the proper products to get it flat tow ready. First, I would recommend the Hopkins wiring harness # HM56200 because we've had better luck with them not having issues after installation. This wiring harness has diodes to prevent back-feeding built in but if you wanted to install more we offer # RM-790 or # RM-690. To wire up the 4-way, that...

  • What is the Difference Between the EZ4 and EZ5 Base Plate Kits for a 2014 Jeep Wrangler Unlimited
  • Since both the EZ4 # RM-521448-4 and EZ5 # RM-521448-5 base plate kits fit your 2014 Jeep Wrangler Unlimited and have removable draw bars there really doesn't seem to be much of a difference at first glance. However, there are some significant differences that are important to take note of. The EZ5 kit is easier to connect your Falcon tow bar to but does not allow the use of the anchor brackets for sterling cables. Sterling cable anchors will have to be attached to the frame or welded...

  • Recommendation For Flat Towing 2009 Jeep Wrangler Behind RV
  • Yes, either braking system will work. Both the Blue Ox Patriot, Item # BRK2019, and the Roadmaster InvisiBrake System, Item # RM-8700, are good options. Both will need power connections so you can connect the Patriot II with a 12V Outlet Kit like Item # RM-9332 and the InvisiBrake will connect directly to the battery. Of the two, I recommend the Roadmaster InvisiBrake System, Item # RM-8700, because it is a one-time install and then you are good to go. Because you will need to...

  • Best Flat Towing Setup for a Jeep Wrangler Unlimited with D-Ring Bumper Mounts or OEM Rubicon Bumper
  • To setup any vehicle for flat towing the basic parts that you need are a Base Plate Kit, Tow Bar, Safety Cables, Vehicle Tow Bar Wiring, a Supplemental Braking System, and most likely a High-Low Adapter. Since your 2014 Jeep Wrangler Unlimited has the 3/4 inch D-Ring bumper mounts you won't need a base plate kit. Instead you will need to use the Adapter for Jeep D-Ring Bumper Mounts # RM-035 with a Roadmaster Tow Bar. I recommend using the Roadmaster Falcon 2 Tow Bar # RM-520 as it is...

  • Recommended Base Plate Kit and Other Parts to Flat Tow a 2008 Jeep Wrangler with Warn Front Bumper
  • Your Warn off-road bumper has shackle mounts. If the mounts are 3/4 of an inch thick you can use the adapter # RM-035 or if they're 1 inch thick you can use # RM-035-1. Both adapters will work with your Roadmaster Falcon 2 # RM-520 with no problem at all. If you don't already have them you'll also need safety cables, wiring, a braking system, and likely a high-low adapter to flat tow the Jeep. The safety cables I recommend at # RM-643. They're coiled which helps keep them off of...

Both do the same thing in basically the same way. Where there is a significant difference is the installation. Our installers prefer the SMI Stay-IN-Play because it is a quicker and easier installation. Because of the easier installation process, I recommend the SMI-Stay-IN-Play...

  • Flat Towing 2010 Jeep Wrangler Sahara
  • First, you will want to make sure that your 2010 Jeep Wrangler will not exceed your towing vehicle's maximum towing capacity. Generally, when flat towing, you want your tow vehicle to weigh twice as much as the vehicle being towed. You will also want to check your owner's manual for instructions on recreational towing for your vehicle. If you find it is safe to tow your Wrangler behind your car, then you will need a base plate kit, tow bar, braking system, tow light wiring, and wiring...

  • Is a Stop Light Relay Needed when Using the Roadmaster Even Brake on a 2009 Jeep Wrangler
  • The stop light relay, # RM-88400, is included with the Even Brake, # RM-9400. You will need to use the stop light switch kit, # RM-751452 according to Roadmaster. This kit will alert you when the vehicle brake pedal is being pressed. A 12 volt power supply, # RM-9332, is also recommended. To determine if a brake light relay is needed to properly wire your towed vehicle, answer the following questions. Are you using a supplemental braking system that depresses the brake pedal in your...

  • It sounds like you have a Falcon 2 Tow Bar # RM-520 that came with your Class A motorhome. The Falcon 2 is rated up to 6,000 pounds so you'll want to make sure your Ram doesn't exceed that. Depending on how its equipped it very well may. Also, make sure your RV is rated high enough to tow the Ram. What you need on your 2008 Dodge Ram 1500 is a base plate kit that will connect to the tow bar. If your truck is a MegaCab # 277-1A will work for you and if you the truck isn't a MegaCab...

The bumper part number will have to be 11540-10 or 11540-11. If it is a different part number then none of the base plates will fit. I have included a link to the instructions to the right. On these base plates you can only use Roadmaster motor home mounted tow bars. I recommend the Falcon 2, # RM-520, that you mentioned. It is...

  • Troubleshooting Even Brake Portable Proportional Braking System On 2015 Jeep Wrangler Unlimited
  • I called my contact at Roadmaster about the # RM-9400 and the troubleshooting message you keep getting. They told me that you need to check the green wire that is coming out of the # RM-751452 switch. You should only show current when the brake pedal is depressed. If you are not showing current, then the switch is probably bad or it has shorted out and needs to be replaced.

In addition to the base plates and tow bar you will also need safety cables, lighting, and supplemental braking to flat tow your 2011 Jeep Wrangler. For cables you can use # RM-643.

Blue Ox makes a universal bolt-on base plate kit, # BX88230, that you may be able to use. It requires that the bumper be reinforced or modified to install. I have linked the instructions for you.

This includes the cord that will stretch between the Jeep and motorhome using the 7-way connector on the back of the coach. In addition you'll need a brake light relay # RM-88400 to keep the Jeep's brake signal from overriding the RV's turn signals. In addition, if the Jeep you decide on is a 2014...

I recommend checking your fuses to determine if one has blown and that is causing the 12V not to show power; your RV's owner's manual should have the fuse locations for you to take a look at. If you do need to run a wire you can do so from your RV's battery by using the right amount of 10 gauge wire # 10-1-1 with Heat Shrink Butt Connectors # DW05745-10 and...
