Roadmaster Flat Tow Brake System - RM-751471

  • Stop Light Switch
  • Roadmaster

Avoid damage to your towed car 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.

The system was not difficult to install. It works well. I have a monitor in the cab of our motorhome to see that the brakes activate when they should. The system has worked flawlessly for over a year. The only issue I have is when I forget to turn the system off during normal driving. The system brakes over my braking and is sort of aggressive. That is my fault though. I would recommend this system to anyone who was considering towing a car behind their motor home.

Still working great, in fact added another unit to second vehicle



by:

Great instructions and videos.



by:

Never seem to be disappointed - great service and written instructions with excellent photos. Videos are great also.



by:

Works just like it should on my 2022 Jeep Cherokee.



by:

Turned out I didn't need this kit for my application. Quinn F was very helpful when this was discovered and was able and was able to grant full refund for the returned kit.



by:

The instruction video was the biggest help. Because I’m very visual without that I’m not sure I could’ve done this. It turned out great and I’ve not had any issues in the last year.



by:

Works great on my 2021 Jeep Cherokee. Makes the tail lights work as they should.



by:

I’m thankful etrailer has the parts I need along with easy to follow videos for installation. However, I was disappointed that although the parts were in stock it took a week before you shipped them out of your warehouse.



by:

The product showed up at the time I was told it would. I installed it and it fit well and seems to be functioning as it should. I have a couple connections to finish and than OPS check. I used this switch instead of looking for a hot brake wire for my brake controller. No one wanted to touch my Jeep to wire the brake controller in as it did not come with a factory hitch and wiring, and that included the dealer! So I added this switch and now there is no need to do anything with the factory wiring! That eliminates the computer on the Jeep from thinking it has a problem from hooking up something extra it was not expecting.



by:

This product worked exactly as described. Some things to be aware of.
1. It's a yellow dichromate plated solenoid. Not plastic grey. Nice
2. The video for the 2018 Cherokee shows a 4 bolt brake booster. 2019 Cherokee has a 5 bolt brake booster that has a black plastic frame. Use the same bolt location in the video and it works great. You'll need a deep socket and extension. 13mm.
3. PUT the solenoid on BEFORE attaching bracket. If for some reason you forget, Have someone depress brake pedal and then there's plenty of room to install.



by:

One year later and I haven't had to touch this system even once. It just works, all the time, every time. Very happy with this kit. Works perfectly in my 2019 Toad (Jeep Cherokee).

  • Flat Towing Components Needed For A 2022 Jeep Cherokee Trailhawk
    Hey Tim, Those are both great choices for getting your Cherokee flat tow-ready, however you'll also need a few more components to complete your setup. If you go with the Blue Ox Avail Tow Bar # BX7420 then you'll want to go with the Blue Ox Baseplate # BX1143 to avoid having to purchase any additional adapters. The Demco Stay-IN-Play Duo # SM99251 is one of my most recommended braking systems but is designed for hydrualic braking systems. If your motorhome has air brakes you would want...

  • Parts Needed to Flat Tow 2014-2018 Jeep Cherokee KL
    Yes, your Jeep Cherokee KL can be flat towed; though you did not mention the year of your Cherokee, the KL started in 2014 and each of the parts I recommend for you will be compatible with 2014-2018 Cherokees. There are a number of parts you're going to need in order to flat tow your Jeep, starting with compatible base plates. I recommend the Roadmaster Direct Connect Base Plate Kit # RM-521447-5 which is compatible with all 4WD Cherokees with the exception of Trailhawk models. If you...

    Hey Mike, thanks for reaching out. I wish I could help here but I am sorry to say we do not have a video that shows pulling the carpet or trim panels back. We do have a video that shows the Brake Light Switch # RM-751471 being installed on a 2021 Jeep Cherokee, but the video is more to show how things are wired, and I do not believe they cover the carpet or panels. I have linked that video for you below if you want to take a look.

  • Locating Cold Side of Brake Light Switch on 2016 GMC Terrain
    If you are unable to locate the correct terminal on your 2016 GMC Terrain's BCM to connect the brake controller red wire to, I recommend testing the brake switch wires beneath the brake pedal with a circuit tester like # PTW2993. Test each wire to see if you can find one that receives power only when the brake pedal is depressed. If you are able to locate this wire, this is where you connect the red wire from the controller to. I was not able to verify the wire color on your Terrain, so...

  • Necessary Equipment to Flat Tow 2020 Jeep Cherokeee TrailHawk Elite Behind Motorhome
    In order to flat tow your 2020 Jeep Cherokee Trailhawk Elite, you'll need base plates, a tow bar, safety cables, a wiring solution so the vehicle taillights will mimic what the motorhome tallights do, a supplemental braking system and possibly a high/low adapter and a few other odds and ends. I'll typically recommend Roadmaster products because they are well-engineered, reliable, easy to use and cost-effective. For a base plate, I'd recommend # RM-521451-5, because it's not terribly visible...

  • Parts Needed to Flat Tow 2019 Jeep Cherokee Limited, Latitude or Latitude Plus
    For your 2019 Jeep Cherokee you'll need to first start with a base plate kit. For that you'd want the part # RM-521452-4. This fits the Latitude, Latitude Plus and Limited models. If you have an Overland, Trailhawk, or Trailhawk Elite you'd want the # RM-521451-5. Next you'll need a tow bar which for that the Roadmaster Sterling part # RM-576 is your best option for if you have the Latitude or Limited models since you'll need the included crossbar. If you have an Overland or Trailhawk...

However, there are many wiring kits, like the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 that will allow you the features to charge your battery while you drive so you are not limited in your hours of towing based on battery.

  • Parts Needed to Flat Tow 2020 Jeep Cherokee
    Hey Brian, it sounds like you are off to a great start but the first thing I noticed is that it doesn't look like you have a lighting solution covered? For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed vehicle. This comes with a round 6-way connector that you will install on the front of your towed vehicle...

    There is a trim level of your 2017 Jeep Grand Cherokee that can be flat towed. You are able to flat tow a Grand Cherokee model with the Quadra-Trac II/Quadra-Drive II with 4-Lo Range. With regard to the special kit for the power steering, there was a Mopar tech bulletin (08-022-16) that states that if your vehicle was built after February 16, 2016, that kit is not necessary. I recommend that you contact your Jeep dealer for clarification. The necessary kit, if you need it, is available...

  • Is Mopar 68321424AB Flat Tow Wiring Kit Needed to Flat Tow a 2017 Jeep Cherokee Latitude
    Although Jeep corrected the problem beginning with the 2019 model, the 2017 Jeep Cherokee Trailhawk will indeed need the Mopar 68321424AB flat tow wiring kit to activate the electronic power steering system while the vehicle is in tow mode. You'll need to obtain the part from your Jeep dealer. To flat tow your Jeep, you'll need a tow bar, base plates, safety cables, a wiring harness to join the Cherokee to the tow vehicle and a supplemental braking system.

  • Can a 2015 Jeep Cherokee Trailhawk 4WD be Flat Towed?
    Your 2015 Jeep Cherokee Trailhawk 4WD can be flat towed if you have the 2 speed transfer case. This differs from the single speed power transfer unit because it has a neutral position. The neutral (N) selection button is adjacent to the 4WD selector switch. If you have this neutral position you are good to flat tow, if you do not then recreational towing is not allowed. You can find this information on page 596 of the online owners manual. If you have the neutral option on your power...

  • What Causes Death Wobble When Flat Towing 2019 Jeep Cherokee
    There was a special harness from Jeep that was designed to address the problem you mentioned when flat towing the newer Cherokees like your 2019 Jeep Cherokee. Here recently they made updates to the vehicle to take care of it without requiring the harness. The harness part number was 68321424AB and it could only be gotten through them.

  • Will I Get The Death Wobble When Flat Towing My 2021 Jeep Cherokee Trailhawk?
    The part you are referring to (Mopar's 68321424AB) was indeed a fix for certain models and years of Jeep Cherokee that were experiencing the dreaded "death wobble", but your 2021 Jeep Cherokee Trailhawk does not fall under these years. Those years were from 2014 to 2018 and the issue has since been resolved, so it will not be needed. This means that once the Roadmaster Direct-Connect Base Plate # RM-521451-5 is installed, along with the rest of a full set up I recommend listed below in...

The Roadmaster Stop Light Switch Kit # RM-751449 you referenced would only be compatible with select Jeep Grand Cherokee's so it wouldn't be a fit for your vehicle.
