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: 13"

Note: This FuseMaster bypass is not designed to hold an ATM micro fuse. If your vehicle has a micro fuse, you will need to use an ATM mini fuse of the same amperage (not included) to install in the FuseMaster.

Some cars can only be towed if you get under the hood and pull a fuse. If you don't remove this fuse prior to 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 car'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 need to drive your car, just make sure the switch on the bypass is flipped into the "drive" position. When on, the fuse will be active and your vehicle will function normally. Then, when it comes time to tow, switch the FuseMaster to "tow." 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. This switch must be mounted on a plastic surface that is no thicker than 1/4". Do not mount the switch on a metal surface.

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, 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.

Ordering and shipping was fast and easy. Products arrived in good condition. I haven't installed them yet, but it all looks as advertised. Not my first order with etrailer and the customer service was outstanding as always. Why anyone would order from any place other then etrailer I cannot fathom.



After one year, I couldnt be happier. etrailer never disappoints!


Easy to install. Perfect fit on my Honda 2014 CRV. Video was awesome. Great information on web site to aid in purchasing the correct one the first time.


I installed the Fusemaster fuse bypass switch on my 2012 Chevy Sonic. Install was a snap. It is mounted on the lower dash to the left of the steering wheel and above the fuse panel. I had to cut the fuse cap off and remove the wire loom to get the plastic nut off the switch. The fusemaster switch will be a great time and effort saver since the DLIS fuse on the Sonic is a pain to remove.


Very easy to install in my gmc 2013 terrain. Took 5 minutes. Hardest part was drilling hole in fuse box cover. I did not have a 3/4" drill bit so has to drill out edges it largest bit I had. Was fine doing this was. Is expensive for what you get, a fuse holder ,switch, plug in and wires?




Prompt order processing and delivery.


Very very pleased with service from purchase to follow up. Product video was informative and very helpful. When and if needed I will be back to etrailer again.


Good Quality. Works well.


Absolutely love our Blue Ox system. Was easy to install (with a little mechanical help) and has served us over 11,000 this past year. We were extremely fortunate that etrailer had a video of our exact year and model which made installation even easier.

We've towed over all sorts of terrain and would absolutely purchase this again and recommend it to anyone who asks!

Perfect product to eliminate the hassle of pulling a fuse each time I tow. Quick and easy to install.


Roadsters product worked well. I did not remove the lower dash part, and just did extreme yoga to remove and install the fuse bypass. This was the worst part. I can't believe that Honda put this fuse block in such a difficult to access location. The rest was simple. Installing the small connectors was a trick, (I also didn't use the fuse connector) but I finally got the connections in the fuse block. Drilled the hole from the outside and installed the switch. The location could have been lower and more to the left as there was a thicket portion of the dash on the back that prevented the lock nut from seating, but the switch is tight and works well. This is absolutely the way to go instead of pulling a fuse on my 2014 Honda CRV!



Product is great. Works well and was a fairly easy install.


Great product, easy to install, works perfectly. Makes it a lot easier to et the CRV ready to tow. Thanks again etrailer for another great product.



Product update, been using this product for a year now. It has worked flawlessly. No issues, just push the button and youre either ready to tow or you are back to normal operation. Highly recommended.


My base plate and tow bar has performed flawlessly since the day it was installed. I took a chance by installing the equipment before picking up my motorhome which was 1,300 miles away - hoping everything would match up as advertised. And it was seamless! First time hook-up went without a problem and the car towed perfectly - and has ever since. I'm totally sold on this Blue Ox towing system!

Absolutely no problems! A solid purchase that I would make again if needed.

Worked as described fairly easy to install. Received earlier than expected also.


What I needed to take care battery drain situation. After checking around, price was comparably a good price, but nevertheless, this item is OUTRAGEOUSLY expensive for what it is, a plastic switch, fuse holder, wire, and some terminals, with a Roadmaster label. No complaints for etrailer, but the Roadmaster part is just too expensive. I guess I knew that when I ordered it, though.



Terminals would not stay in place regardless of how they were ed. I modified the terminals by using a mini-fuse tap that worked like a plug. Inserted the supplied terminals into the tap, then secured them with electrical tape. Next, I cut off the wire pig-tail on the tap. The mini-fuse tap actually fits in micro-fuse with a click, and is much more secure than the spades supplied by Roadmaster. For the price, it should have come with plug, instead of having to modify the tiny spade connectors.

Thanks for the follow-up after a year of use, and for the additional information!

Pete P.


Absolutely outrageous price and I have to do the same modification to the connection to the fuse panel using a mini fuse connection. The original design is terrible.


New switch fit perfectly. Operated great. Thanks


I love the fuse bypass. I used it in my Honda CRV which requires a fuse to be pulled each time the car is towed, then replaced when you want to use the radio. Once installed, taking out the radio fuse is a simple push of a switch. The only problem I encountered was gettin the two loose ends into the fuse socket, and once there I felt it necessary to jam in some foam to keep them in place. It would help if Roadmaster would connect the leads like an actual fuse. Other than that it works exactly as advertised.



So right you are. I could not get the two loose ends into the fuse socket. It was designeed for a Mini Fuse not the MICRO fuse in my Honda Fit. Roadmaster need to fix this with an actual fuse-like connector end.


Great Product, and Service & Price


Very cool! No fuse box yoga! Seriously did honda have to put the fuse that needs to be removed in the most inaccessible place? this solves that issue.


The connection to the field Box with the For spade Connection is iffy and has a tendency to fall out or short circuit. I had to go out and buy a type of type of connection that is meant for another purpose so that I could get those bad bits into that and it would lock it in to the fuse Box


I had the BEST installation and service at Etrailer. This was made more evident when a friend got her new hitch from a DIFFERENT RV store. She Towed to the campground and did not fully know how to unhitch or hook up. Etrailer not only taught me all I needed to know about my hitch but took the time to have me learn first hand, with my own hands, how to hitch, unhitch and drive hitched. Etrailer had me drive with a technician and try different procedures behind the wheel — to learn the full do’s and don’ts. Thank you Etrailer.


Worked well. I did not like the fuse position as it was inaccessible when the bypass was installed so I moved the fuseholder position in the wire nearer to the fusebox end so that I could access it after installation. I watched the etrailer video which was useful but I wanted the switch installed in a blank switch panel rather than down low as shown in the video. I was concerned about the size of the hole to be drilled in the blank switch panel but it worked out well. I use plastic epoxy rather than the supplied nut to hold the switch in place. This also strengthened the drilled out blank switch panel. Only 4 stars because I had to make these mods, but the result is a nice installation using the supplied fuse bypass parts.


I installed this in my Honda CRV. Unfortunately, this cuts off power to the Radio and the 12 volt outlets. I could not use it because of my Tow Vehicle Braking System needs 12v power to operate. I fixed the problem by installing charge lines on my RV and in my CRV.

  • Installation of Roadmaster FuseMaster Fuse Bypass RM76511 in 2018 Chevy Sonic Automatic
    The FuseMaster bypass # RM76511 is not designed to hold an ATM micro fuse so if your 2018 Chevrolet Sonic has a micro fuse, you will just need to use an ATM mini fuse of the same amperage value (not included) to install in the FuseMaster # RM76511. The DLIS fuse that needs to be pulled is fuse position 1 according to the online manual I reviewed, however the manual does not mention the fuse type or specific amp value.

    Thanks for your recent order! The Roadmaster fuse bypass # RM76511 is great because all you need to do is flip a switch to activate or deactivate the fuse. It's not a requirement though and based on my research, your owners manual doesn't say anything about pulling fuses to flat tow your 2011 Ford Flex. I also checked with Roadmaster and fuses don't need to be pulled. It's still a good idea you check your owners manual just in case. I included a helpful article and installation video...

  • Fuse Bypass Wires Do Not Seem Very Secure in 2013 Honda CR-V Fuse Panel
    You really don't have anything to worry about because while you are flat towing your 2013 Honda CR-V power to that fuse will be shut off. Should the connectors come out it would not matter since there is no power to that fuse. But when just driving the vehicle it could be an issue should the wires come out. You might be able to get a better connection if you can get some of the other fuses out of the way so you have room to work the terminals in better, then put the other fuses back. Our...

  • What Typically Unlocks Steering Wheel to Allow Vehicle to be Flat Towed

  • Towing a Ford Edge with a Blu Ox Patriot Brake System Causes Battery Drain
    That is a very short time to drain the battery. I took a look at the owner's manual for a 2014 Ford Edge and it does say that leaving the key in that position will drain the battery, so it is very odd that would be a requirement from Ford. Still, to answer your second question first, for some cars there will always be power at the 12V circuit and others it does not. To answer the first question, yes, you can remove the fuses that the accessories are draining the power from or use a fuse...

  • Will Using Roadmaster Fuse Bypass Shut Off Clock and Cause Radio Presets to Be Lost
    It very well might. Different circuits are affected in different vehicles. The reason you pull the fuse or bypass it is to prevent the vehicle battery from being discharged while its being flat towed. Try pulling the involved fuse first for a few seconds, and then replacing it. If you lose the clock and radio presets, you know that using the fuse bypass will cause the same thing.

I spoke with my contact at Roadmaster and he confirmed that if you need to pull a fuse before towing your 2006 CR-V, the # RM76511 fuse bypass will work well for you.

    If you're going to be listening to Taylor Swift you might need a higher fuse rating! But seriously the fuse bypass for your 2012 Honda Fit, # RM76511, is rated for a maximum 20 amp fuse. But, you really only have to pull the fuse if you will be towing for more than 8 hours. Otherwise you can pull over somewhere and then start up the Fit to let the alternator charge up the battery. Be sure to follow the flat towing prep information from the owner's manual prior to towing the vehicle again...
