Roadmaster Tow Bar Wiring - RM76510

Take some of the hassle out of towing your car with this fuse bypass system. FuseMaster replaces your vehicle's mini-fuse and lets you prep for towing by simply flipping a switch. Integrated holder keeps fuse secure and functional.


  • Bypasses towed car's mini-fuse so you can tow your vehicle without draining its battery
    • Provides a simple alternative to removing a fuse every time you tow
    • Stores fuse so that you won't lose it
  • Installs quickly, easily and permanently
    • Remove fuse from car's fuse box and install FuseMaster in its place
    • Put fuse into FuseMaster fuse holder
    • Mount bypass switch near fuse box
  • Maintains functionality of mini-fuse when switched on
    • Flip switch to "Drive" position and drive like normal
  • Overrides mini-fuse when switched off
    • Flip switch to "Tow" position and you're good to tow
  • Made in the USA


  • Application: ATM mini-fuse not exceeding 20 amps
  • Harness length: 10"

Some cars can be towed only if you get under the hood and pull a fuse. If you don't remove this fuse before towing, there's a good chance that your battery will be drained by the time you reach your destination.

Roadmaster's FuseMaster makes it easy to prep your vehicle for towing. Simply remove the fuse indicated in your owner's manual and replace it with the bypass. The system will hold the removed fuse and maintain its functionality. So, once the initial installation is complete, you don't have to remove or replace your fuse again.

Whenever you want to drive your car, just make sure the switch on the bypass is flipped into the "Drive" position. When the bypass system is on, the fuse will be active and your vehicle will function normally. Then, when it comes time to tow, switch the FuseMaster to "Tow." Doing this will render the fuse inactive so that you can flat tow your car without its battery being drained.


The preferred location for mounting the FuseMaster switch is the access panel inside your vehicle that leads to your fuse box. The switch must be mounted on a plastic surface that is no thicker than 1/4". Do not mount the switch on a metal surface. Drilling is required.

Roadmaster FuseMaster Switch

Included with the FuseMaster are 2 stickers: "Drive" and "Tow." Once the switch is installed, you can place the stickers on the access panel - one on each side of the toggle - to remind you which way the switch must go for each application. Place the "Drive" sticker on the side of the toggle that has the white dot. (To drive your car, the switch must be flipped so that the side with the white dot is depressed.) The "Tow" sticker can then be placed on the opposite side.

Video Transcript for Roadmaster FuseMaster Fuse Bypass Installation - 2008 Chevrolet HHR

Today on our 20008 Chevrolet HHR we're going to be installing the Roadmaster Fuse Master fuse bypass switch for towed vehicles, part number RM76510. Our switch is currently in the drive mode and we have it hooked up to our tow vehicle. We'll flip it into tow mode, which will disconnect the power going to the fuse port number 8 so it doesn't drain the battery while the vehicle's being towed. Then once you're finished with towing the vehicle and you're ready to drive it again, simply flip the switch back, which again sends power back to the fuse port through the bypass fuse. First we'll go ahead and locate the manufacturer's fuse box panel. The fuse box panel is located on the passenger side on the inside of the console. We'll go ahead and remove the panel by gently pulling out and releasing the fasteners underneath.

Turn it over we can see the four fasteners that secure the panel in place. Next we need to locate fuse pin location number 8. This is for the key pass system, and the one that will be turned off when the vehicle is being towed so that it doesn't drain the battery. All the way to the right of our fuse box, third right top, is a gray 2-amp fuse. This is pin location or fuse location number 8.

Now in order to install the fuse bypass what we'll do is remove our 2-amp fuse and replace it with the pins or terminals here at the end of the fuse bypass harness. Once everything is installed we'll then take the 2-amp fuse, put it into the fuse amp holder, and we'll have our switch mounted. Now mounting location will depend on accesibility between the length of your harness and where it's applicable to mount the switch, because you'll need enough length behind the mounting to allow for the harness and switch itself. To mount the switch we can remove the harness. We'll drill a 3/4" hole in the mounting and use the switch nut that's provided to sandwich it in the panel and secure the switch in place. For this application for the room that we need and the access to the driver we're going to mount it here in the panel.

I'm just going to hold it in place, then go by feel, make sure I've got plenty of room, mark my spot. Now with my panel marked I'm going to go ahead and drill out the hole for the switch. I'm going to start with a pilot bit and a small hole first. Now once our hole is drilled out we'll go ahead and install the switch. Once we have the switch in place we'll turn it over and use the nut to secure it. Now with our switch mounted and installed and secured, we're going to go ahead and install the labels.

We've got one for drive and one for tow. We can remove the label. I'm just going to attach it right above the switch for my drive and right below the switch for when the vehicle is being towed. Now with our switch installed we're going to move back to the vehicle, go ahead and remove the fuse, and install the harness into the fuse port. Again, we're going to the third from the top all the way to the right and removing the 2-amp fuse. Once this fuse is out we can take the wiring harness pins, which will replace the pins from the fuse. Now with the wiring harness installed into the fuse port we'll go ahead and take the two pigtails for our switch and reinstall them. Then we can put our fuse that we removed from the fuse box into the fuse holder. Put the cap on the fuse holder and then reinstall the fuse panel. There you have it for the install and operation of the Roadmaster Fuse Master fuse bypass switch for towed vehicles, part number RM76510, on our 2008 Chevrolet HHR. .

Do you have a question about this Tow Bar Wiring?

  • How to Flat Tow a 2015 GMC Terrain
  • According to the online manual for the GMC terrain that I reviewed the vehicle can be flat-towed once a few preparation steps are taken, including removal of fuse 32 to prevent battery drain. I suggest you refer to your owners manual, specifically the section identified in the index as Recreational Towing, just to confirm that your particular Terrain is suitable for flat-towing and to become familiar with the steps necessary. For a base plate kit I would recommend the Roadmaster Base...

  • Parts Needed to Flat Tow a 2014 Chevy Sonic with Blue Ox Tow Bars
  • I have a solution for you, but the Roadmaster EZ-5 Base Plate kits like part # RM-523173-5 can not be used with a Blue Ox tow bar. For your 2014 Chevy Sonic you would want to use the Roadmaser EZ-4 Base Plate kit part # 523173-4 and then use the Roadmaster Tow Bar Adapter # RM-032 to allow you to use it with a Blue Ox tow bar. There are a few other components needed to flat tow your vehicle. You will need to pull a fuse to tow your vehicle so you would want the Roadmaster FuseMaster...

  • What is the Right Fuse Bypass to Flat Tow a 2008 Chevy HHR Behind a Motor Home
  • For a 2008 Chevy HHR you will need FuseMaster # RM76510 to bypass the fuse that normally would have to be pulled in order to flat tow the vehicle. Please consult the HHR owners manual to confirm that fuses do in fact have to be pulled to flat tow the car as well as for other important information on flat towing the vehicle. I have included 2 helpful links on flat towing as well as a link to the installation instructions for the FuseMaster.

  • Recommendation for Supplemental Braking System on 2013 Chevrolet Sonic
  • The continuous power assist braking system or active power assist system works by monitoring your day-to-day braking habits to formulate a normal braking pattern. The system will detect a change in your rate of braking force and your position on the brake pedal and interpret this as an emergency situation. If the system feels that there is not enough pressure being applied to the brakes, it will initiate an override mode and activate the vehicles full braking force. Typically, a supplemental...

  • Difference Between Standard Brake Controller and Supplemental Braking System Flat Towing Honda CR-V
  • The difference between the Blue Ox Patriot # BRK2012 that you referenced and a standard brake controller that sends the signal through the blue wire has to do with how the units work with the different brakes. The Patriot works with hydraulic brakes that are in vehicles and standard brake controllers work with trailers with electric brakes. The Patriot will not work on trailers and standard brake controllers will not work on automobiles. The Blue Ox Patriot # BRK2012 that you referenced...

  • Which Fuses Need to Be Removed to Flat Tow 2011 Cadillac SRX
  • According to my Roadmaster representative, there are three fuses, all of which are located in the fuse box under the dash. You'll look for the BCM1, BCM2 and BCM3 fuses, all of which are 15 amps. Roadmaster recommends the # RM76511 (bypasses 1 fuse) and the # RM76512 (bypasses 2 fuses) fuse bypasses. I'll link you to some articles about flat towing. I hope you'll find them helpful.

  • Parts Needed to Flat Tow a 2014 GMC Terrain
  • You have most of your bases covered, but you are missing one component to complete your flat towing setup for your 2014 GMC Terrain. You still need a lighting option. For your vehicle I would recommend the Hopkins Custom Tow Bar Lighting Kit part # HM56108. This is a custom install kit that would install without any cutting or splicing and would activate your towed vehicle's taillights in conjunction with your tow vehicle's. I attached an FAQ article on how to pick out the best tow...

Then you can say goodbye to the aching back! I have linked a video that shows an installation. The vehicle is different in the video but the process will be similar.

  • Fuse Bypass Switches Recommendation For 2015 Chevrolet Malibu
  • To use a fuse bypass for the 3 fuses you need to remove on your 2015 Chevrolet Malibu you will need 2 of the bypass units we offer. I recommend the Roadmaster FuseMaster Bypass, part # RM76511 for one of the 20-amp mini-fuses and part # RM76512 for the other 2 20-amp mini-fuses that have to be removed. As far as mounting, the only indication given for mounting locations is to make the switch accessible. It really is dependent on the vehicle and where you have the room for these...

The use of this product will make it easier to bypass the fuse by allowing you to bypass it instead of pulling it every time.

  • Parts Needed to Flat Tow a 2015 Chevy Sonic Behind a Motor Home
  • To flat tow a vehicle behind a motor home you will need 5 items: base plates, tow bar, safety cables, lighting, and supplemental braking. For base plates for your 2015 Chevy Sonic you can use Blue Ox base plates # BX1703. I have included a link to the installation instructions for you. For a compatible tow bar that comes with safety cables I recommend the Alpha, # BX7365. I have included a link to a video review featuring this tow bar for you. For lighting our installers prefer...

  • Would the Roadmaster Fusemaster # RM76510 fit a 2003 Honda CR-V
  • I checked with Roadmaster and they do not list your 2003 Honda CR-V as needing a fuse bypass for flat towing so they don't have a recommended bypass switch like the # RM76510 that you referenced. However, if you have ATM mini-fuses in your vehicle this product would work for if you wanted to deactivate a circuit easily. I attached an install video for you to check out as well.

  • Can 2014 GMC Terrain be Safely Driven After Removing Fuse 32 for Flat Towing
  • Fuse 32 inside the in-cab fuse panel on the 2014 GMC Terrain is for the ignition switch. It appears to control a switch related to the key position in the ignition. The vehicle will still start and run but something related to the ignition will not have power if you do so. Therefore it is not recommended to drive without it. You can install a bypass switch # RM76510 to disable power to this fuse rather than having to pull it and put it back in every time. When flat towing the vehicle...

If the fuse you are pulling is not an ATM mini-fuse, let me know what it is and I can determine if we have a bypass that fits.

  • Mini-Fuse Bypass Switch Recommend that Enables a Circuit to Be Turned Off with a Switch at Fuse Box
  • The Roadmaster FuseMaster Fuse Bypass # RM76510 that you referenced would do exactly what you are looking to do and is designed for use in a mini-fuse slot on a fuse box. However, for your situation this would be just a Band-Aid. I would recommend you fix it permanently as it may be a sign that eventually the wipers will just stop working which could be dangerous if you were caught in a storm.

  • Can Battery on 2015 GMC Terrain be Charged While Flat Towing it Behind a Motor Home
  • Check the owners manual for the vehicle you intend to flat tow because you may or may not have to disconnect the battery to flat tow it. If you do not then it is possible that there is some feature that could drain the battery while in tow. And of course if you do have to disconnect the battery it would not drain. To provide a maintenance charge to the vehicle while in tow you would attach a charge wire to the battery and connect it to the Terrain side connector included with wiring...

  • Plug-In Tow Bar Wiring for a 2007 Chevy HHR
  • The connectors that plug into the tail light wiring in Hopkins tow bar wiring kit # HM56100 for the 2007 Chevy HHR are not available by themselves. You would need the whole kit. If you want to hardwire in a kit you could use # HM55999 but that actually costs more than the plug-in style kit. Consult your owners manual because it also looks like you will need to pull a fuse to flat tow your HHR. To make this process as easy as flipping a switch you can use fuse bypass # RM76510.

A 12 volt outlet kit # RM-9332 is also recommended because the regular 12 volt outlet on the vehicle will either have no power or not enough power for the braking system when the vehicle is set up in the tow position.

  • What Fuse to Pull to Flat Tow a 2012 GMC Terrain
  • I would make sure you are pulling the correct fuse, the fuse you need to pull is the number 32 fuse like you said, but you will want to make sure that it is the fuse labelled ignition switch. It sounds like your accessories are still on with the fuse pulled which makes me think you may have pulled the wrong fuse since those accessories shouldn't have power with the fuse pulled. Instead of pulling the fuse every time you tow you could install a Roadmaster Fusemaster part # RM76510...

  • A flat towing set up would not be cheap because in addition to the base plates and tow bar, to legally tow a vehicle you also need safety cables, lights, and supplemental braking. The Ambassador tow bar # BX7302, fits Blue Ox base plates spaced 24 inches apart on center. Base plates # BX1703 are 23-1/2 inches apart on center so it would not work. The tow bar I recommend is the Alpha, # BX7365. It includes safety cables. And for inexpensive lighting you can use a magnetic kit, # C-ATL20A. Check...

According to Blue Ox and Roadmaster, either one of these light kits should fit just fine inside the tail lights on your Traverse.
