Features to know about

Always Know When You''re Braking: Activation for RV Brake-Monitoring System

Peace of mind while towing starts with transparency. The Roadmaster Stop Light Switch Kit activates your RV's brake-monitoring system whenever the brake pedal in your towed car is engaged. So, you always know exactly when the brakes are applied in your towed vehicle, ensuring safe travels every time.

Protects Against Costly Damage: Monitors Supplemental Braking System

Installing supplemental braking systems can sometimes result in improper positioning, causing continuous pressure on the brake pedal. This kit ensures that your supplemental braking system is functioning correctly, helping to prevent unnecessary pressure on the brake pedal that could lead to vehicle damage.

Perfect for Custom Towing: Direct Wiring into Fuse Box

For those towing setups without a dedicated tow position in the ignition, this kit wires directly into your vehicle's fuse box, tapping into a constant current for foolproof operation. It’s an ideal solution for maintaining reliable functionality during custom towing applications.

Easy and Reliable Setup: Made in the USA

Proudly made in the USA, these parts not only guarantee exceptional quality but also uphold rigorous manufacturing standards. Whether you''re a DIY enthusiast or depend on professional installation, you''ll be confident in a straightforward setup that won’t let you down.

Tailored for Your Vehicle: Custom Fit Applications

Designed to fit precisely with your vehicle, this kit delivers dependable performance for your specific make and model, avoiding the one-size-fits-all pitfalls. Its 12-volt system offers the necessary customization and integration, catering to your unique towing needs.

  • Recommended Complete Flat Towing Setup for a 2024 Jeep Wrangler
    Hey Christian, welcome to the world of RV-ing! So in addition to the Roadmaster Nighthawk # RM-676 you're also goin to need: - A baseplate kit, like the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5. These attach to the Jeep itself so you can hook up the tow bars. - A braking system, like the Demco Stay-IN-Play Duo Flat Tow Brake System for RVs w/ Hydraulic Brakes # SM99251 with the stop light switch # RM-751490. This braking system is a bit more involved set-up wise, but once...

  • Recommended Parts Needed to Flat Tow a 2018 Jeep Wrangler JL or JL Unlimited
    For your 2018 Jeep Wrangler JL, I recommend starting with the Roadmaster EZ5 Base Plate Kit # RM-521453-5. 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...

    We have all of the parts you need to flat tow your 2020 Jeep Wrangler, and while it may seem like a lot of parts, it's actually just four basic components - base plates on the Jeep, a tow bar to connect the Jeep to your motorhome, wiring to power your Jeep's lights while it is being towed, and a braking system.

  • Parts Needed to Flat Tow 2018 Jeep Wrangler JL With BrakeBuddy Supplemental Braking System
    To flat tow your 2018 Jeep Wrangler JL you will need to start with compatible base plates; because you have a Blue Ox tow bar and assuming you have the standard factory bumper the best option is the Blue Ox Base Plate Kit # BX1139 which will be compatible with Blue Ox tow bars Alpha # BX7380, Avail # BX7420 as well as Aventa, Aladdin, Adventurer, Ambassador, Acclaim, Allure, and Trion. If your Blue Ox tow bar does not have integrated safety cables you will need those and can use the Blue...

  • Correct Roadmaster Seat Adapter for BrakeMaster System on a 2018 Jeep JL Wrangler Unlimited
    Hey Kevin, thanks for reaching out! You'll need the Seat Adapter # RM69FR for your 2018 Jeep JL Wrangler Unlimited. This is used for both the BrakeMaster # RM-9160 and the BrakeMaster # RM-9060 for motor home air or hydraulic brakes respectively.

  • Is The Brake Light Relay Needed With The Roadmaster 4 Diode Wiring Harness On 2018 Jeep Wrangler JL?
    Good question, Chuck! You will not need the Brake Relay # RM-88400 when installing the Roadmaster 4 Diode Wiring Harness # RM-15267 on your 2018 Jeep Wrangler JL Unlimited. This is because the stop light switch circuit on your Jeep JL will go dead while the vehicle is in tow. With that being said, some of the braking systems will require a stop light switch, like the # RM-751490 (and a 12 volt outlet kit # RM-9332)), but that is dependent on which system it is. Do you already have a...

    Hey Ed! It looks like you put together a great list of parts. I'm going to list everything out here with links so it is all in one place, including my suggestions.

  • Is Roadmaster Brake-Lite Relay Needed for Flat Towing 2020 Jeep Wrangler with Push Button Start
    The Roadmaster Brake-Lite Relay # 88400 that you referenced actually isn't needed for your 2020 Jeep Wrangler Unlimited 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 the written installation manual below along with an install video that you can follow along with.

  • Comparing Direct-Connect and Crossbar Base Plates for 2018 Jeep Wrangler JL Unlimited
    The difference between the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5 and Roadmaster Crossbar-Style Base Plate Kit # RM-521453-4 is how tow bars attach. As the name suggests, you will connect your tow bar straight to the direct-connect base plates while the crossbar style will require you use your tow bar's crossbar or quick-disconnect. This makes the direct-connect the easiest base plate to connect to and disconnect from. Because of that, for your 2018 Jeep JL Wrangler Unlimited...

  • Recommended Custom Tow Bar Wiring Kit for a 2021 Jeep Wrangler Unlimited
    Hey Patrick, so I took a peek and what we have for you and I was able to find the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM39VR which is a custom fitting harness that plugs into your existing wiring without splicing. As far as the Roadmaster Stop Light Switch Kit # RM-751490 goes, you are going to need that with your Roadmaster Even Brake Portable Flat Tow Brake System # RM-9400 to complete install. You're also going to need the 12 Volt Outlet Kit, 20 amps # RM-9332.

  • 2018 Jeep Wrangler Unlimited Sahara JL Wiring for Flat Towing
    For your 2018 Jeep Wrangler Unlimited Sahara JL flat tow wiring, you will need the Roadmaster Stop Light Switch Kit # RM-751490 which will communicate with your motorhome's brake monitoring system that your Jeep brakes are being applied. This is to help you know if a problem is occurring like your Jeep brakes constantly being applied so you can solve an issue before damage occurs.

    Since you already have a Stowmaster tow bar and Blue Ox Patriot there are just a few more parts you will need though I would need a bit more information from you to get you exactly what you need.

  • Will the Flat Tow Equipment for a 2021 Jeep Wrangler Transfer to a 2024 Jeep Wrangler
    Wayne, the Roadmaster InvisiBrake Flat Tow Brake System # RM-8700 with the Roadmaster Stop Light Switch Kit # RM-751490 you have will transfer just fine from your 2021 Jeep Wrangler to your 2024 Jeep Wrangler. I'm also looking at the wiring and base plates, and it appears that all that should transfer as well.

  • Which Roadmaster Base Plates For 2024 Jeep Wrangler Sahara For Flat Towing
    Hey Don, So the Roadmaster # RM35GR only fits Jeeps with that have a factory steel bumper that has a winch on it. Your 2024 Jeep Wrangler Sahara won't have that so the correct base plates are the Roadmaster Direct-Connect Base Plate Kit # RM-521453-5. As for the wiring, that is correct the Curt harness does not mention ParkSense as it is not for those Jeeps with Parksense. If you have the ParkSense you will need the Roadmaster Smart Diode 7-Wire to 6-Wire Wiring Kit for Variable Voltage...

  • Recommended Wiring Harness and Baseplate for a 2024 Jeep Wrangler Sahara
    No, sorry Tony. You'll need to use a 6-way connector especially if your model Wrangler has ParkSense or LED lights. I recommend the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit item # RM-15267 or if your Jeep has the ParkSense Proximity Sensors, the Roadmaster Wiring Kit for Variable Voltage LED Tail Lights item # RM63MR. We have two options for Demco baseplates that fit your 2024 Jeep Wrangler, which one you need is going to depend on your bumper. I have listed both below: Factory...

    To flat tow your 2020 Jeep Wrangler you'll need a tow bar, base plate, tow bar wiring kit, braking system, and safety cables. The etrailer SD Non-Binding Tow Bar # e34ZR is a great choice for your tow bar. It has non-binding latches that make unhooking on any terrain easy and telescoping arms that make hooking up on any terrain easy. This tow bar also comes with safety cables so you won't need to purchase any separately. The etrailer Invisible Base Plate Kit # e98948 is a fit for a...

  • Troubleshooting An Error Message With A Demco Stay-IN-Play Duo Coachlink Monitor
    The 2020 Jeep Wrangler Rubicon doesn't have a useable brake light switch wire so the coachlink monitor in your Demco Stay-IN-Play DUO # DM86VR is most likely sending this error since it isn't getting the brake signal. You'll need to install the Roadmaster Stop Light Switch Kit # RM-751490 and connect it to the red wire of the transmitter so that it can properly communicate with the coachlink monitor.

  • Is The OEM Brake Switch Usable When Flat Towing A 2022 Jeep Wrangler?
    The OEM brake switch on your 2022 Jeep Wrangler is not usable for this purpose. You will need to use a brake light switch # RM-751490. This will send the proper signal to the supplemental braking system. I have linked our review and install video below if you want to take a look.

  • Recommended Permanently Installed Braking System For A 2023 Jeep Wrangler Unlimited
    Excellent! We have just the thing. For a permanently installed system I recommend the Roadmaster invisibrake # RM-8700. This will be tied into your RVs brake light signal and will activate every time the brake lights illuminate. The actuator box installs permanently in an out of the way location and a plunger and cable connect behind the brake pedal. You really will not know its there once you install. Please note that with the 2023 Wrangler Unlimited, the OEM brake switch is not usable....

    If your 2020 Jeep Wrangler Unlimited Willys edition has a factory plastic or steel bumper then the Blue Ox Base Plate Kit # BX1139 would be a compatible fit for your vehicle. The Blue Ox Tow Bar Wiring Kit # BLU79FR you referenced would also be a fit for your Jeep but I recommend cutting off the 4-pole connector and wiring this kit into a 6-pole socket and 7-way cable kit like part # RM-146-7. This would allow you to also run a charge line cable like part # RM-156-25 so that you Jeep's...

    There unfortunately are no plug-and-play wire harnesses available for a 2024 Jeep Wrangler with ParkSense Proximity Sensors at this time so you'll need the Roadmaster Wiring Kit with Smart Diodes for Variable Voltage LED Tail Lights # RM47ZR. You should have the socket and umbilical cord with your Nighthawk tow bar, but if you don't you'll need part # RM-146-7 as well.
