Roadmaster Tow Bar Braking Systems - RM-751490

  • 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:

  • Application: custom fit for your vehicle
  • 12 Volts


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.

Works great fairly easy install. It has been in use for the last 8 month's with no issues. Here may be some helpful hints that I found when installing. Use 10-12" long extension for 13mm nut (left side of opening panel that was removed). Install bracket. Adjust plunger & backing nut by feel. Remove bracket. Install switch with ring washer & nut. Crimp red & green wires on switch wires. Reinstall bracket under dash.




by:

I installed it myself to tow my 2018 Jeep Wrangler as I had experience as an auto mechanic myself years ago. I would not reccomend self install for those without such eperience even though the online videos were helpful. The only issue I had with performance was sticking lock mechasims which was resolved by calling the manufacturer, who instructed cleaning the housings which got dirty.




by:

I installed this system my self with great instruction off etrailer YouTube. Ben a solid working system, no issues and A few thousand miles on the meter.




by:

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).




by:

Great product and thanks to etrailer.com for the excellent videos detailing how to install the Demco Stay-In-Play Duo braking system. As a result of watching all of the available videos, I learned that there where a couple of different ways to install the system in our Jeep Wranglers. The first installation I did was in our 2019 Wrangler and that was super easy following the one video on your website. The second installation of the system was not as easy because our 2021 Wrangler has a manual transmission and required having to drill a hole in the firewall/floor board to run the wiring and vacuum tube from the passenger compartment to the engine area. If etrailer.com ever has an installation on a Jeep Wrangler with a manual transmission to perform, hopefully they will video tape that installation to guide customers with Jeeps with manual transmissions. I think etrailer.com's idea of mounting the control box on the fuse box is by far the cleanest and easiest way to install the Demco braking system.
I also followed etrailer.com's videos for installing the brake light system and the base plate on both our Wranglers and could not be happier with them. Thanks etrailer for all you offer.




by:

Great product installed very easily. I also used this switch to install a Brake Controller. By using this I did not have to tap into the Wrangler electrical system for the Bake Controller.




by:

Package is great, component checklist was important to me and clear color instructions as well as the install videos provided at time of order confirmation are what sets your company apart from the others. Sorry it took me so long to discover etrailer. Thank you!

Fit great,




by:

The item was purchased specifically for a 2018 Rubicon JLU. Here are the flaws:
1. The bracket holes are the same size yet the instructions state use the larger hole for the switch side. A micrometer confirmed such. The angle and length of each bracket end varies slightly so you have to struggle with placing the switch on each bracket end and test for fit and switch adjustment parameters. Roadmaster could easily mark the appropriate end and assisted the customer.

2. The wires provided are to short for a proper fit specifically from the battery to the switch. Its a confined space and room to work with a short lead on the switch and a short power wire. Had to use a longer wire run and trim off once the power wire was routed and through the firewall.

3. Roadmaster knows the fuse terminal connection provided will not work in the JL yet provides it verses providing an inline blade fuse holder. That means a trip to the auto parts store since the kit in incomplete for a fuse holder and don't forget to have on hand the proper length of power wire to complete the installation.

4. There is also an electronic component which obstructs (behind the trim panel)accesses not described or illustrated in the installation instructions/video. It has to be moved to gain proper access. Not a big deal but there are 4 delicate plugs to remove so be cautious.

Overall-The bracket is solid and engineered so that the switch aligns with a metal tab on the brake pedal. Dissatisfied with the accompanying accessories-Roadmaster really short changed the customer with these components.




by:

This product is good quality overall. Installation is tough. I've got big arms and big hands and trying to get the bracket on the stud is all but impossible. Tip: wire the switch BEFORE installing the bracket and switch. Adjusting the switch is equally as difficult. Otherwise, it is a straight forward install.


Comments
So far the product has been performing as advertised. We towed from south Florida to Colorado and back with multiple stops and side trips and no issues at all. We even went 4-wheeling in CO for a day and nothing worked loose. Id recommend this product, with some modifications suggested by Rad.

I went to E Trailer for my Trailer needs because of the quality of products and variety of options for my needs. Most of all the service is outstanding. The Ladies I delt with were so qualified and knowledgable and able to answer any question asked of them. Very patient in dealing with someone who has little knowledge of just what was needed to achieve my end requirements. You not only get what you pay for, quality, but fast follow up service. Thank You Ladies you all are a precious asset to E Trailer. I am very pleased with the products & service. John 4B15

I had my shop that works on our rig, they said it was easy to install.




by:

If you are pleasing plump as me and arthritic, give yourself some time, not hard to install actuall if I were 40 still would be a 10 minute job




by:

Installed on my 2021 Jeep Wrangler Sport. Only thing I’d change is to strip the wires on the switch and make butt connections before mounting on the bracket. It’s a really tight space for hands under the dash.




by:

The installation videos make it SO easy! It took time for me since I'm a perfectionist but it turned out flawless. I saved over $1000 by installing it myself and etrailer made it possible!!! They covered everything I needed to do the job! Highly recommended etrailer every time!




by:

Installation and function have been without issue.




by:

Great products and good how to information on installing




by:

Works as advertised and installation was easy with to-the-point instructions.




by:

Lets you know your brakes and controller are functioning properly.




by:

Kayla’s was very helpful in identifying the parts needed for my Jeep, Roadmaster flat tow project and followed up with an email to confirm delivery was made. Thank you.




by:

Haven’t installed yet but it appears to be the device I ordered.




by:

Hey, y’all give great service, thanks and merry Christmas




by:

Fairly easy installation, however using a proximity switch instead of the mechanical plunger switch would make adjusting the switch easier




by:

Maybe one of the best e-commerce businesses I’ve ever dealt with!!!!!

  • How to Locate Brake Light Switch on 2019 Jeep Wrangler for Installing Brake Controller
    In order to install the Tekonsha Prodigy P2 Brake Controller # 90885 on your 2019 Jeep Wrangler I actually recommend using the Roadmaster Stop Light Switch Kit # RM-751490. The cold side of the brake light switch is next to impossible to actually access on the new Jeep Wranglers, so you can use the Brake Light Switch Kit to provide the controller with the needed stop light signal for operation. I have attached the complete installation manual and a short video below so you can see exactly...

  • Do I Need to Use the Roadmaster Brake-Lite Relay # 88400 on My 2021 Jeep Wrangler?
    The Roadmaster Brake-Lite Relay # 88400 that you referenced actually isn't needed for your 2021 Jeep Wrangler with the push button start. In order to ensure proper operation of the signal lights and braking system you instead need the Stop Light Switch Kit # RM-751490. I have attached an installation video of the switch to walk you through the installation process.

  • 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.

  • 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. Ideally I could...

  • Does The 2021 Jeep Wrangler Unlimited Need A Brake Light Relay For Flat Towing
    No, the brake light relay Item # RM-88400 is not used for the 2021 Jeep Wrangler Unlimited because the brake wire cannot be spliced into. Instead you would want to use the Roadmaster Stop Light Switch Kit Item # RM-751490. Now you would only need this if you are using a permanently installed braking system. If you are using a portable system then you would not need it.

  • Switch Kit Needed To Send Braking Signal When Flat Towing A 2018 Jeep Wrangler JL With InvisiBrake
    The reason you're not getting a signal from your 2018 Jeep Wrangler JL to your Roadmaster InvisiBrake Supplemental Braking System # RM-8700 monitor in your 2019 Holiday Rambler Vacationer is because the OEM switch isn't compatible and will instead require the Roadmaster Stop Light Switch Kit # RM-751490 to send the signal.

    The Roadmaster Stop Light Switch Kit # RM-751490 is indeed required when installing the Roadmaster InvisiBrake Supplemental Braking System # RM-8700 on your 2021 Jeep Wrangler Unlimited. This is due to the brake light switch shutting off after 10 minutes of inactivity and while being flat towed.

  • How To Prevent The Brake Lights From Overriding The Turn Signals Of A 2020 Jeep Wrangler Unlimited
    The stop light switch # RM-751490 you referenced is just for signaling you when the brake is being depressed because the brake light switch wire is either too small a gauge (i.e too weak) to splice into to send the braking signal. The Roadmaster Brake-Lite Relay Kit for Towed Vehicles # RM-88400 is what will stop the braking signal from overriding your turning signals. Since your turn and brake lights are "combined" they use the same wire to activate. This kit just allows the signals...

  • Will Roadmaster InvisiBrake Work on 2021 Jeep JL Wrangler with EcoDiesel
    I check with Roadmaster and the Roadmaster InvisiBrake Supplemental Braking System part # RM-8700 will be a great option for a 2021 Jeep JL Wrangler with EcoDiesel. They stated they don't typically recommend this for diesel engines but there is electric brake assist on these so it will still work. It will however require the Roadmaster Stop Light Switch Kit part # RM-751490 for proper operation.

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 the...

  • Solution to Deactivate Stoplight Indicator for Supplemental Braking System When Not Towing
    Since what you are wanting is to prevent the brake light indicator of your supplemental braking system from illuminating when you aren't flat towing it the simplest solution we can offer is to wire in a switch on the power wire of the light like with part # D16740. This will easily allow you to kill the light whenever you don't want it and then flip it on when flat towing.

    The Roadmaster Stop Light Switch Kit part # RM-751490 that fits your 2023 Jeep Wrangler is designed to provide a dedicated stoplight circuit for supplemental braking but was not designed for activating a light in the windshield like what you described. Normally it is the permanently installed supplemental braking systems like the Demco SBS Stay In Play part # SM99251 that have the light setups like what you are wanting that show when the braking system is being used.

    The Roadmaster Stop Light Switch Kit # RM-751490 is what is required for your 2021 Jeep Wrangler Unlimited, and not the # RM-88400 you mentioned. This is due to the stop light switch on your Jeep timing out of after so long.
