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.

  • 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...

  • 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...

  • 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.

  • 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...

  • Parts Needed to Flat Tow a 2014 Chevy Sonic Behind a Motor Home
  • 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 least expensive compatible tow bar is the Adventurer, # BX7322. For safety cables you can use # RM-643. And for inexpensive lighting you...

  • Towing a non-SS 2010 Chevy HHR Behind a Motor Home
  • No, the Chevy HHR and HHR SS are fundamentally different were the base plates install so you would not be able to use the SS base plates, # 523159-1, on a non-SS model. I have verified this with my contact at Roadmaster. For a non-SS model you would use base plates # 3141-1. For a compatible tow bar I recommend the Falcon 2, # RM-520, and safety cables # RM-643. For lighting you can use a magnetic lighting kit # C-ATL20A. Or for a more permanent solution you can use diode kit # RM-154....

  • 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.

  • 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.
