Roadmaster Flat Tow Brake System - RM-751475

  • 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:

  • 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.

Great Product very adjustable for mounting on all types of vehicles!



by:

Had an issue with expedited shipping. Once I received the part I contacted etrailer and it was resolved within a couple minutes.



by:

Some pieces from this kit were needed for installing a brake Controller in a 2016 Sprinter, without the tow package. It works and the van doesn't flag any errors or codes. I talked to a helpful etrailer rep before buying to confirm my application and that personalized service was much appreciated.



by:

Installed in 2016 Ford Edge Titanium. Had to buy additional cable connectors that were not included in the kit and instructions did not specify they were required. I would have given 5 stars if it was at least mentioned in the instructions.



by:

Ordered parts for installing a brake controller.
The videos that are part of the web site were a great help in selecting all the needed parts, detailed down to the part numbers that were needed.
I really like the fact that there is a video showing the brake controller installation with my specific vehicle.
Great service !



by:

This is a great device. The reason I bough it from ETrailer is because of customer service. They are super helpful.

Place the brake as suggested and try it out. Works just as expected.

It fit perfect in my 2022 Lincoln Nautilus! And the instructions were excellent and well done! Thank you folks !!

  • Parts Needed For Installing Trailer Hitch Receiver & Wiring For Brake Controller 2022 Sprinter 2500
    Since your 2022 Mercedes-Benz Sprinter 2500 did not come with the factory tow package you may not have a connector for the brake controller under the seat or under your dash. I have linked an installation video for the Redarc # RED44FR at the bottom of the page which will show you where the connector is and if you can wire it in using the Pigtail # 3063-P and Adapter # 331-TPH-017. As I see you were looking at the Prodigy P3 # 90195 it would only require the Pigtail # 3063-P which is long...

  • Parts Needed to Install Brake Controller 2024 Mercedes Sprinter 3500
    I checked with Redarc and a few other brake controller manufacturers and they state that your 2024 Mercedes Sprinter 3500XD does not have an OEM brake controller install port under the dash like previous models so you would have to hardwire in the Redarc Tow Pro Liberty part # RED24FR with the install harness # RED69FR and the brake controller install kit part # 5506 which wires to the OEM 7-way you have. We've also heard that the stoplight switch circuit is hard to find on your vehicle...

  • Can A 2023 Lincoln Nautilus Be Flat Towed?
    Hello Raymond, a 2023 Lincoln Nautilus can be flat towed, but only if it is a 2.7L V6. The 2.0L AWD and FWD models cannot be flat towed and must be towed with all 4 wheels off of the ground, such as using a car trailer. If yours is a 2.7L V6, you can flat tow using the manual park release procedure highlighted on page 218 of your owner's manual. You will want to put your climate control system in recirculated air mode to prevent exhaust fumes from entering the vehicle. Also, you can never...

  • Will the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles Work on a 2015 Ford Edge SEL
    I do have an option but the Hopkins Custom Tail Light Wiring Kit part # HM56011 will only fit the 2015 Ford Edge Sport/Titanium, not the 2015 Ford Edge SEL. The 2015 Ford Edge SEL has variable voltage taillights which is where the issue lies. Therefore, you will need to use the Roadmaster Wiring Kit part # RO44FR which requires splicing. There are no plug and play flat-tow wiring harnesses for a 2015 Ford Edge SEL unfortunately. I have attached some other parts you might need as well below. Roadmaster...

  • Recommended Electric Trailer Brake Controller for a 2016 Mercedes-Benz Sprinter with Tow Package
    It sounds like you're looking for an electric brake controller for your 2016 Mercedes-Benz Sprinter. There isn't a confirmed plug and play wiring adapter for your van. If you have a connector under the dash send me a picture of it and I'll see if we have something that will work for you. Since you have the tow package with a 7-way trailer connector you'll just need the wiring kit # 5506. You'll also need a brake pedal switch # RM-751475 because of the wiring system of the van.

  • Recommended Parts to Flat Tow a 2017 Ford Edge Titanium
    Yes, disconnecting the battery with a Quick-Disconnect, like the Deka part # DW05312, will be the easy way to go when it comes to disconnecting the battery on your 2017 Ford Edge so it can be flat towed. Disconnecting the battery prevents it from draining while you are flat towing. Since the owner's manual states that the battery must be disconnected I strongly recommend following those instructions and not trying to get by it somehow. That is one of the down sides to flat towing with...

  • Can The Tekonsha Prodigy P3 Brake Controller Be Installed On A 2017 Mercedes-Benz Sprinter 3500?
    This is actually an issue with the Mercedes-Benz Sprinter 3500 in the 2017 model year if it was not equipped with the factory tow package. Due to the vehicle's wiring system, as you mentioned, you will need the stop light switch kit # RM-751475 to bypass the factory switch. Typically modification of the included bracket will be necessary for installation, but this is pretty easy to do. Once this is installed, you will have absolutely no problem using your Tekonsha Prodigy P3 # 90195.

  • Roadmaster Parts For Flat Towing 2023 Ford Edge ST
    Yes, per the owner's manual I looked up, so long as you have the 2.7L engine you can flat tow your 2023 Ford Edge ST. The warranty will not be affected, and Roadmaster does indeed have the parts for your vehicle. To make it easy for you to order, I'll go ahead and list them all out: - Base Plate Kit: Roadmaster Direct-Connect Base Plate Kit # RM-524460-5 - Tow Bar: Roadmaster Falcon All Terrain, Non-Binding Tow Bar # RM-522 - Roadmaster Safety Cables # RM-645 - Wiring Kit: Roadmaster...

  • Trouble Locating Cold Side of Stop Light Switch for Brake Controller on 2014 Mercedes-Benz Sprinter
    There are some wires that are hot all of the time which is why we usually try to emphasize that the brake controller, like the Prodigy P3 # 90195, needs to be connected to the cold side of the stop light switch when installing the Kit # ETBC7. Sometimes a vehicle will not have a wire connected to the cold side of the stop light switch which is what you are finding. In that case you will simply need to install the Roadmaster Stop Light Switch Kit # RM-751475. This is typically used for...

  • How To Install a Brake Controller on 2017 Mercedes-Benz Sprinter 3500
    You can hard-wire in a brake controller, and it seems that there are not a lot of the Sprinter 3500 models that are pre-wired, at least from what I've seen in my research. I have not seen any reports that this isn't possible, and we even have an installation video to walk you through the process. The way to find out whether or not the plug is present by using a circuit tester like the # PTW2993 and testing for a hot wire when the brake is pressed- it's possible that one of the plugs that...

  • Recommended Items Needed To Flat-Tow 2015 Ford Edge Titanium
    When flat-towing your 2015 Edge, the tow bar wiring you need is part # RM-154. My contact at Roadmaster verified it will be what you need with the LED lights. There are 5 items needed when flat-towing a vehicle. You will need the base plates, tow bar, safety cables, lighting, and most states now require a supplemental brake system. In case you do not have the items needed I will make recommendations that will work well for your Edge. The base plates I recommend are part # RM-524454-4....

  • Trailer Brake Controller Installation in 2017 Mercedes-Benz Sprinter 2500
    There is no plug-and-play brake controller harness for the 2017 Mercedes-Benz Sprinter 2500 so brake controller installation will be a hard-wire process. Under the driver's seat there should be a green plug. The wires to this plug can be tested with a circuit tester like # PTW2993 to confirm their function since vehicle wire colors are not always consistent. A brake controller like the Prodigy P2 # 90885 has 4 wires that require connection to the Sprinter. The black wire is 12V input...

  • Adding a Brake Controller to a 2012 Mercedes-Benz Sprinter with 7-Way Trailer Connector
    Since your 2012 Mercedes Sprinter does not have the wiring to plug in a brake controller but does have a 7-Way trailer connector you will need to do a little hardwiring to install a controller such as # 90195. You will need installation kit # 5506. From the kit you will use the wire, 30 amp circuit breaker, and ring terminals. On the brake controller the white wire will ground to the negative battery terminal. The black wire will connect to the positive terminal via the 30 amp circuit...

  • Recommended Battery Disconnect For 2016 Ford Edge Titanium
    For your 2016 Ford Edge Titanium, when using the Roadmaster InvisiBrake Supplemental Braking System # RM-8700 you will still need to use a battery disconnect because it states it in the owners manual. I reached out to my tech contact at Roadmaster to confirm. Each vehicle is different whether this is required or not. Since it is required on your vehicle I recommend the # RM-766. You will also need stop light switch # RM-751475 for this application. I've attached a video to help.

  • How to Install a Brake Controller on a 2016 Mercedes-Benz Sprinter 2500
    If your 2016 Mercedes-Benz Sprinter 2500 came with a factory 7-way trailer connector then there should be a green connector located under the driver's seat. This green connector would then be plugged into a Mercedes-Benz speciality harness and attached to a brake controller. However, if you do not have this connection or cannot find it then you will want to proceed with the hardwire option. In order to hardwire a brake controller such as the Tekonsha Prodigy P3 Trailer Brake Controller...

  • Is Brake Light Required when Using a Supplemental Braking System on a 2017 Ford Edge
    You will not need to use the brake light relay on your 2017 Ford Edge and SMI Stay-IN-Play DUO braking system # SM99251. But since your vehicle brake lights do not light up with the ignition off you will need to use the stop light switch kit # RM-751475. The switch kit activates the motor home brake-monitoring system whenever the brake pedal in your Edge is applied which ensures that the supplemental braking system is functioning properly.

  • What Is Needed To Pull A Trailer With Electric Brakes Using A 2016 Mercedes-Benz Metris?
    In order to tow a 4000lb trailer with your 2016 Mercedes-Benz Metris, you first need a hitch. I would go with the Curt Trailer Hitch Receiver Class III - 2" # C13276. This is the highest weight capacity hitch we offer and has a max tongue weight of 900lbs and max towing capacity of 6000lbs. In order to get a 7-Way Plug-in on your Metris, you first need to install a 4 Pin trailer wiring kit if your vehicle does not already have one. I recommend going with the ZCI 4-Pole Flat Trailer...

  • How to Power Blue Ox Patriot Braking System on Ford Edge when Disconnecting Battery Cable
    Since your 2017 Ford Edge requires that the negative battery cable be disconnected to tow the vehicle, you will just need to add the 12 Volt Outlet Kit # RM-9332 for use with your Blue Ox Patriot Portable Braking System # BLU37TR. This kit is needed to provide power to the braking system with the vehicle battery disconnected. The kit attaches directly to the battery terminals to provide the needed power. In order for the Blue Ox Patriot System to work properly on your vehicle, you will...

    As long as your 2019 Mercedes-Benz Sprinter 2500 has a factory plugin connection point for the adapter part # 3063-P you will not need to make any modifications to the adapter, it will plug right in into the factory plug and the other end to a Tekonsha, TrailerMate or Draw-Tite brake controller. The plug that the harness will use is located under the driver seat. It is a green four pin plug which can be seen in the attached photo. If you do not have this factory plug then the green plug...

  • 7-Way Trailer Connector for a 2017 Mercedes-Benz Sprinter 2500
    In order to install a 7-way trailer connector on the rear of your 2017 Mercedes-Benz Sprinter 2500 to your existing 4-way, you will need the Adapter 4-Pole to 7-Pole and 4-Pole part # 37185. Unfortunately, they do not make a wiring harness that splices into the taillights and give you a 7-way trailer connector therefore this will be your only option. If you will be towing a trailer with brakes then instead of part # 37185, you will want to use the Universal Installation Kit for Trailer...

  • Can Blue Ox Flat Towing Parts from 2013 Ford Edge Fit a 2018 Ford Edge SEL
    You will be able to use your Blue Ox braking system and tow bar but you will need new base plates. The 2013 and 2018 Ford Edge SEL use different base plate designs. Base plates # BX2657 work with SEL models that do not have Active Cruise Control or the 2.0 EcoBoost motor. And they will not fit models with the Driver Assist Package. If your 2018 does have Active Cruise Control but not the EcoBoost 2.0 liter motor then you can use base plates # BX2667. These base plates will be compatible...
