Most Popular Roadmaster for 2021 Jeep Wrangler

I have a 2016 Jeep Wrangler Sport Unlimited 4 door, after I installed the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles - HM56200, I found I had to install the Road-Master Brake Lite Relay for Towed Vehicles - RM-88400 , I'm using a supplemental brake system, when the brake is depressed with ignition off, the brake lights come on and cancel out any directional signal on my toad, installing the relay solved this problem. I watched the video and this was helpful. Installation took me a few hours, climbing under the dash was not an easy chore for me, I'm not as young as I want to be, had to purchase 16 gauge Red wire to run to Fuse box under the hood, also I recommend having extra wire ties to do this. I recommend both products, easy to install and good quality.

I use the Blue Ox Patriot II supplemental braking system in my Jeep Wrangler Unlimited; so, it override the brake lights within the Jeep when the RV tail lighting and Patriot are in operation. This simple relay does the trick. The installation video was perfect for the installation. The only problem I ran into was crimping that the Jeep's braking signal wiring was 18 gauge, which was kind of loose in the 16 gauge (blue) butt connector. Used my own 18 gauge (red) connector instead. No problems.

Just received it, and have not begun to assemble and install. I will have a few questions. The shipping was VERY FAST. The unit looks to be in good shape. ( no damage that I can see) etrailer is a very good place to purchase stuff, and spend money. BECAUSE........You get the best value for your money, and they can answer questions. Tom

I do virtually all my own maintenance on all 7 of my vehicles. This installation is not conceptually difficult, but working under the dash of a Jeep Wrangler is literally painful. The hardest part is figuring out where to mount the controller and route the brake cable. My Jeep is not the same as the video and I needed to install it a little differently. Take your time here and get it right the first time. I made several modifications to the standard installation - including hooking all the signals (including the Monitor) from my truck camper to my towed Jeep through a 7-Pin RV connector and hooking the power to the Invisibrake through a switch to the battery so I don't have to run my Parking Lights to power the controller. I had a couple questions that the folks at Roadmaster answered cheerfully and professionally. BTW Etrailer is a pleasure to do business with.

I bought a complete flat tow parts fir a jeep wrangler. I decided I could install myself. Your installation videos made it nearly a piece of cake. From a quote I got from a RV service business, I saved several thousand dollars installing myself. etrailer is the place to for your RV needs!

Works as it should and easy to install and remove

Excellent packaging and informative videos available for installation. Made it easy and I saved $$$$ for professional installation doing it myself.

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

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.

Kit fits great! Hooked up a 2004 Workhorse to a 2002 Jeep Liberty. It might be preferable to be handy with some advanced mechanical skills and tools to install this efficiently. Directions are great but you do need to figure out your own locations for certain items like the break-away reservoir, compressor, routing lines and wires out of harms way, but not bad at all. Parts are great, everything there but added a couple different wiring splices of my own.

Your customer service leaves nothing lacking, and this follow-up from you is so out of character for the many web sites I have purchased from over the years. I am impressed by you and your company. I bought the tow bar and the brake system for my Equinox, and installed them my self (I am 70 years old) - and with your provided instructions and video, I had no problems (even though I was surprised by the number of parts and detail that went into the assemblies). Both systems have worked very well, with no problems. I am completely satisfied with them, and have told my friends and traveling acquaintances about your company. Thanks for your follow-up!

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).

Install was tight in the Wrangler. I would recommend removing the driver seat, it at least removing the seat bolts and moving it rearward to have room to work.

Installation was tight on the Fiat 500 but the instructions were right on. No issues since installation. It's performing well.

Perfect, and the followup by etrailer second to none. It is nice to have their expertise in your corner.

Installed it on my 2020 Jeep Gladiator. I had bend the bracket slightly to ensure the button was pressed evenly. Otherwise, works as it should.

The product itself is great, but I’m missing a part that I ordered.

Easy to install. This product is a lifesaver! My JGC WK did not have the tow package installed, so it had no connection for an EBC. This product gave me the stoplight switch connection I needed! It took about 20 minutes to install and adjust. Thanks!

Every thing needed was included. You need to be a bit of a contortionist but if this 75 year old can install it you can.

I purchased this as part of a package which included; Hitch and wiring for my 2022 Equinox, Base plate, Tow Bar, brake System and connecting air hose, break away cables, LED tow lights with wiring harness, and a trickle charger to keep the Equinox battery from going dead while I was towing it behind my class A RV. I had etrailer do the install of all the components on my car and RV. All the workmanship was excellent and done in the amount of time they said it would take. Also because they did not have a video of this equipment being put on this year and model vehicle, I gave them permission to make a video(which added a extra day and a half to the install)and the installation was free. Everything has worked perfectly and I couldn't be happier. Etrailer is my go to for anything towing and also RV parts.

Stoplight switch kit was easy to install. All contents needed was supplied.

What is there to say except the Roadmaster stop light switch kit simply works and works flawlessly.
