Roadmaster Tow Bar Braking Systems - RM-751421

  • 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.

  • Will Roadmaster Stoplight Switch Kit part # RM-751421 Fit 2017 GMC Sierra
    The stoplight switch kit part # RM-751421 that you referenced has been tested on your 2017 GMC Sierra 1500 by Roadmaster and they found that it is completely safe to use and works well. It does not tie into the truck's stoplight circuit at all so it would not interfere at all either.

  • Stop Light Switch Kit for Flat Towing a 2015 Chevy Silverado 1500
    Your 2015 Chevy Silverado 1500 requires the use of a stop light switch kit # RM-751421 because there isn't the appropriate signal at the brake switch while the truck is set up for flat towing. Basically the way it works is when the brake pedal is moving on the truck it pushes in on a little sensor that completes a circuit (power for it comes from the truck) to power the indicator on a supplemental braking system.

  • How To Tap Into The Brake Light Switch Of A 2009 Chevy Silverado 1500

  • Parts Needed to Flat Tow 2013 Chevy Silverado Behind Motor Home with a Roadmaster Falcon 2 Tow Bar
    As long as the total weight of the truck and all of its cargo, if any, weighs under the 6,000 pound limit of the Falcon 2 tow bar then you can use it to flat tow your 2013 Chevy Silverado. But first you will need to check the owners manual for the proper procedures for flat towing the truck. For base plates you can use Roadmaster base plate kit # 3154-1. These base plates feature removable arms so the base plates are almost invisible with the arms removed. They are also compatible with...

You will also need a stop light switch kit. This alerts the monitoring system if the brakes on your Tahoe are applied. If you have adjustable brake pedals the kit you need is part # RM-751220.

  • Can a 2011 GMC Yukon 4x4 with Single Speed Transfer Case Be Modified to Flat Tow?
    You are correct that the 2011 GMC Yukon 4x4 with single speed transfer case cannot be flat towed as is. I've attached a photo of the pages from the owners manual to assist. It is logical to think because the 2 speed transfer case models can be flat towed without issue that dropping the drive shaft as you stated would allow you to safely tow your single speed vehicle. Without proper testing, I can't confirm this would be the case, but it is very logical. If you decide to tow it, I recommend...

  • Base Plate Kit and Other Parts Needed to Flat Tow a 2010 Chevrolet Silverado 1500
    With the Roadmaster Sterling, part # RM-576, I recommend the MX kit, part # 3154-3, for a base plate kit that fits your 2010 Chevrolet Silverado. The safety cables of the Sterling won't fit with these but you can attach the cables somewhere else on the truck. The wiring kit to power the truck's lights that I suggest is the diode kit, part # RM-15267. It provides a 6-way connector at the front of the truck and a cord to connect the RV's 7-way to that 6-way. For a supplemental braking...

  • Parts Needed to Safely Flat Tow a 2010 Chevrolet Silverado 1500
    You will need to check your owners manual or with the Chevrolet dealer to see if your 2010 Chevrolet Silverado 4x4 can be flat towed. Some vehicles must be equipped with a transmission lube pump, an axle disconnect, drive line disconnect or free-wheeling hubs before they can be towed. If the correct procedure is not followed it will cause severe damage to the transmission. If you will be able to flat tow your vehicle, you will need a tow bar, base plate kit, safety cables, wiring, and...

  • Parts Needed to Flat Tow a 2009 Chevrolet Silverado 1500 LTZ
    Hopefully my dog doesn't eat it. In addition to the tow bar, supplemental braking, and wiring you also need a base plate kit and likely a high-low adapter to tow your 2009 Chevy Silverado. Since you're towing a full size truck you want a tow bar with a higher capacity so I recommend the Roadmaster Blackhawk, part # RM-422. It's rated up to 10,000 pounds. For the safety cables used the coiled # RM-643. The MX Base Plate Kit, part # 3154-3, pairs well with the BlackHawk. The MX kit...

  • Recommendation For Flat Towing 2007 Chevrolet Tahoe 4x4 Behind Motorhome
    I reviewed the 2007 Chevrolet Tahoe owner's manual and it can be flat towed. To flat tow your Tahoe, you will need base plates, a tow bar, safety cables, wiring, a braking system, and maybe a high-low hitch adapter. For your 2007 Chevrolet Tahoe 4x4, I recommend the Roadmaster MX Base Plate Kit, ItemĀ # 3154-3, because it is designed for your vehicle. It is built with heavy-duty applications in mind. The front arms are easily removable when not in use. The Roadmaster Nighthawk All...

  • Is it Possible to Flat-Tow a 2015 Chevy Silverado 1500 Behind a Motorhome?
    You can tow your 2015 Chevy Silverado 1500 behind your motorhome if it is four-wheel drive, so long as you have a 2-speed transfer case with a neutral setting. While it is also possible to do so with a two-wheel drive version, it will take an extra step. For a 2WD with a 4.3L V6, as well as a 2WD with a 5.3L V8, you will need to have a lube pump kit installed, or for a 6.2L V8, you will have to have a drive shaft disconnect. A base plate kit such as the Blue Ox, # BX1710, is a confirmed...

  • Base Plates, Tow Bar, and Accessories Needed to Flat Tow a 2012 Chevy Silverado 1500
    Before flat towing any vehicle you will want to consult the owners manual to determine how the vehicle should be towed and if there are any special restrictions or requirements. The Roadmaster XL base plates, # 3154-1, bolt onto the frame rails in the front of the 2012 Chevy Silverado 1500. The kit comes with all the parts and hardware for installation.

  • Parts Needed to Flat Tow a 2012 Chevy Silverado 1500 Behind a Motor Home
    Given that your 2012 Chevy Silverado 1500 could easily get over the 5,000 pound limit of the base plates you're refering to I recommend going with a different set. The Roadmaster MX base plates, # 3154-3, are generally considered more heavy duty and are recommended for trucks and SUVs. For a compatible tow bar, you will want a Roadmaster model that slides into the hitch on the RV. For a compatible tow bar that will match the capacity of your hitch and cover the vehicle weight, take a look...

  • Recommended Parts for Flat Towing 2012 GMC Sierra 1500 4x4 Behind Motorhome
    To flat tow your vehicle, you'll need a tow bar, base plates, safety cables, a wiring solution so that the truck taillights work in conjunction with those of the tow vehicle, a supplemental braking system and possibly a high/low adapter. For Blue Ox parts starting with the tow bar, I'd go with the Blue Ox Avail, part # BX7420. This tow bar has a 10K capacity like you were looking for, and features non-binding self aligning arms that make hooking up and detaching very easy. The safety cables...

    Yes you can absolutely use a Blue Ox Tow Bar like the Blue Ox Ascent Non-Binding Tow Bar - Motorhome Mount # BX4375 with your Roadmaster Direct-Connect Base Plate Kit, you will just need an adapter to adapt the tow bars to the base plate. I took a look at what Roadmaster Base Plates are offered for your vehicle, and it appears you'll have either the: - Roadmaster Direct-Connect Base Plate Kit - Removable Arms # 3154-3, Or the, -Roadmaster Crossbar-Style Base Plate Kit - Removable Arms...
