Do I Need a Fuse Bypass Switch?

Technically, it is optional, but if you need to pull a fuse on your vehicle when you flat tow, this kit will make your life so much easier. Instead of wedging yourself down on the floorboard and fishing a tiny fuse out from under your dashboard every time you flat tow (not to mention putting it back again), you can just flip a switch. No dead battery, no lost fuse, no damaged fuse, no back pain.


When the switch is in the drive position, the fuse will be active and your car will function normally. When you're ready to flat tow, you'll flip the switch to the tow setting and deactivate the fuse. This allows you to tow your vehicle without the battery draining.


How to Wire a Bypass Switch for Fuse Disconnect

Installing this fuse bypass switch really only takes a few steps:


1. Open the fuse access panel and remove the designated fuse

2. Connect the end of the wiring harness to the fuse socket

3. Mount the switch in your dashboard

4. Insert the pulled fuse into the fuse holder

I recently ordered the Blue Ox fuse by pass switch for my Honda CRV. My order was sent out promptly and the staff at e trailer were knowledgeable and friendly! Please note: If you have a 2013 Honda CRV, this install takes a while due to the position of the fuse panel .Honda uses the mini fuses and you must purchase a standard fuse to place inline.....no big deal but, small hands and a contortionists body would make installation very much easier.



by:

The switch was for a mini fuse car, mine has the squished mini fuses and took forever to get the wire prongs into the fuse block. I have a 2010 CRV and was disappointed, but it works for now, (until the prongs fall out)



by:

Great product, installed in 5 minutes. Will really save me a lot of time and keep me from getting on my knees with a flashlight and straining to pull and later reinstall the fuse! Item was installed in my 2012 Equinox.



by:

The Blue Ox Accessory Kit for the Aventa LX Tow Bar, the extra (2) Diodes, the Fuse By-Pass Switch, the Aventa LX Tow Bar and the Patriot Brake Unit all arrived in tact and in a timely manner. I really appreciate the help in defining what I need to tow my '09 Yukon behind our new Newmar Dutch Star. So far the wiring is complete - and works! I hope to have the Tow Bar hardware done this week - i'll try and get a picture. Thanks again!



by:

This product works great for the purpose it is intended. Unfortunately, removing fuse #34 also disabled my 12v accessory and made it impossible to use my Blue Ox Patriot II. Weird because there are separate fuses for those. Therefore I have to return it.



by:

I installed your device in a Buick Terraza to disengage the power sliding door control when the intermittent alarm sounds while driving. It saves me from having to pull over and pull the fuse. Thank you for your product.

Purchased and installed in my 2010 Chevy HHR. Was an easy install, directions are very clear. This allows me to leave the key in the correct position while the vehicle is under tow by my RV and not drain the battery. However, I later determined that this meant my HHR brake lights would not operate when the brakes are applied by my Brake-Buddy system. I did install wiring from the RV to the brake lights of the HHR but that did not run the third/middle brake light. So I ultimately decided to install a system that connects my RV power to a charger on the HHR battery so I could leave the power on and have all my brake lights operating. As it turns out I could have done without this item. So it would be a choice of this item or an RV powered charging system depending upon how you would like your brake lights to operate.



by:

Once again wiring too short for a 2014 Honda CRV to install it where there video shows also it was missing the connector to the fuse block. Wasted tiem and money splicing longer wires in.



by:

Fuse Bypass switch works great no more dead batteries, I have used it many times in the last year and I can pull my Honda CRV 8hrs or more and battery stays charged. very easy to install. took less than 1 hour to install



by:

Pins are a pain to keep in while installing. Should have a dummy fuse to plug in with the wires connected to the pins. Also, the fuses don't match the ones they are bypassing in my car. I use micro fuses in my panel and the fuse holders take mini fuses.
The concept is GREAT however and a real time saver removing the time spent on your knees in the dirt fishing around to find the two fuses you need to pull out of the fuse panel and wearing the fuse panel more and wore with each pull.



by:

Easy to install with great directions. Etrailer has great Customer Service even after the sale. Perfect for what I needed....now I don't have to take out the fuse every time I tow my car behind the Motorhome! Great experience with etrailer.



by:

Works great, easy to install.



by:

I have installed the Custom Tail light warning and the Trailer connector and it was very easy. I ran the wiring through inside the FIT wiring and it was very easy. Love the way everything snaps together.

I can't wait to install the base plate, trailer hitch receiver as well as the ByPass switch.

All these items will make our Motorhome experience much easier. Thanks etrailer

Thanks again to Amanda for keeping an eye on my order.



by:

Was very easy to install, works like it should.



by:

As advertised delivered quickly



by:

Age of [online vendor], when items ordered and have expected delivery day, then it takes more than 24hrs to ship during business week. That’s a fail.



by:

sed on my 2016 Ford C-Max Energi to stop pulling fuse 67 the Passport fuse to reset the MY FORD MOBILE APP and regain control over charging the battery.
( I charge my vehicle at 1 in the Morning ). Pulling that fuse 4 or more times a year to get things working was a real pain not to mention removing the cover each time. Since Ford never resolved the problem
with the communication issue this was a great fix. Thanks etrailer and Bule Ox this is a great work around.



by:

Purchased this harness not for a trailer, but for my failing BCM (body control module). My car's headlights remain on even after I leave it. The solution was to put in the headlight fuses every night and unplug them at every stop, or pay upwards of $xxxx for the dealer to replace it (dealer specific part I could not replace it myself as my keys needed to be synched with new module.) Being right in the middle of the pandemic and just before losing my job, spending that kind of cash wasn't an option.

The solution in the end was this $xx harness. The whole unit stays snug under my dash and I cut out a hole for the switch. Every night it's just one extra switch I have to flip instead of getting upside down on the ground and pull fuses. Payed for itself. Very, very happy.



by:

The Blue Ox fuse bypass switch was just what I needed. The delivery was quick and installation was made easy by the instructions and video. Works as described and I will be trying out soon on our next trip towing our 2012 CRV. Thank you etrailer for making my life easier.

The postman brought my package
earlier than I expected! Real happy with that. The box was damaged in shipping but the product inside was OK. The packing was very good. I installed the Blue Ox switch and I am ready to tow my Traverse with the motorhome.

  • Blue Ox Fuse Bypass Switch Wire Gauge
    Hi Charles; I reached out to Blue Ox and they were unable to tell me the wire gauge on the Blue Ox Fuse Bypass Switch # BX88274. They said their specs list it as a "a standard universal size." Based on the 50A rating and short length it’s almost certainly 8 AWG. What are you using it for?

  • Parts Needed to Flat Tow 2013 GMC Acadia AWD
    Yes, the setup you mentioned is complete for flat towing your 2013 GMC Acadia. The base plate kit part # BX1708 is a confirmed fit and will work great with the Blue Ox Avail # BX7420 tow bar that you mentioned. This is the nicest tow bar around so you'll really like it and it comes with safety cables. For wiring the Blue Ox Tow Bar Wiring Kit # BX8848 and the umbilical adapter # BX88206 would have you covered. Instead of having to manually pull the fuse the part # BX88274 would then...

  • Fuse Bypass Kit to Bypass 50-Amp and 15-Amp Mini Fuses in 2011 Buick Enclave
    For your 50-amp fuse you can use Blue Ox ByPass Switch # BX88274 and for your 15-amp mini fuse Blue Ox # BX88272. The Roadmaster FuseMaster Fuse Bypass Switch # RM76514 that you referenced does provide 2-fuse bypass capability but its amperage rating for both is 20-amps.

  • Parts Needed to Flat Tow a 2013 Buick Enclave Front Wheel Drive
    To flat tow your 2013 Buick Enclave you're going to need a tow bar, base plates, wiring for the lights, a supplemental braking system for the brakes, and possibly a high-low adapter. I suggest the Blue Ox # BX1708 for a base plate kit. To connect to the RV I like the Avail # BX7420 for a tow bar because of the 10,000 pound weight capacity. The Avail also includes safety cables. To power the lights of the Enclave use the diode kit # RM-154. According to an online owner's manual for a...

  • Fuses To Pull When Flat towing a 2013 Buick Enclave
    Your 2013 Buick Enclave does not have a dedicated circuit for the hazard lights so we can only assume that they are on the blinker circuits. You would have to consult your local Buick dealership for more specific information. However you referenced the Blue Ox # BX88274 Fuse ByPass Switch For Towed Vehicles, so I am wondering if you were also wanting to know what fuses to pull when flat towing your Enclave. I looked in the Enclaves Owner's Manual on page 10-70 and it says, “To prevent...

  • Fuse Bypass for Flat Towing 2011 Honda Fit
    What you need is a fuse bypass. If your fuse is 20 amps or less you can use the Blue Ox Fuse ByPass Switch # BX88272. However, based on what other Honda Fit owners have reported it sounds like you have a 30 amp fuse. If that is the case, you will need the Blue Ox Fuse ByPass Switch - High-Amp Fuse # BX88274 which can handle up to 50 amps.

  • What Fuses on a 2013 Buick Enclave Need to be Pulled Before it Can be Flat Towed
    I checked the owners manual for a 2013 Buick Enclave and you will need to remove the 15 amp OnStar and ECM fuse. These are in the battery compartment behind the passenger seat on the floor. You will also need to remove the 50 amp BATT1 fuse from the underhood fuse block. For your 50-amp fuse you can use Blue Ox ByPass Switch # BX88274 and for your 15-amp mini fuse Blue Ox # BX88272. What this will do is allow you to deactivate these circuits with just a switch instead of having to...

  • Recommended Wiring for Flat Towing a 2017 Buick Enclave
    I looked at the online owner's manual for your 2017 Buick Enclave and found (on page 298) that there were 3 fuses that are recommended to be pulled for when you flat tow your vehicle. Because of this I recommend installing the Blue Ox # BX88274 and the Roadmaster # RM76514 to help make this process much easier. For the wiring kit to activate the lights on your Enclave I recommend the Flexo-Coil Wiring Kit # RM-15267. Once this is installed you will only know it is there by the 6-Way connector...

  • Recommended Fuse Bypass Switch for a 2009 Honda Fit
    You are correct in that the Roadmaster FuseMaster Fuse Bypass part # RM76511 and the Blue Ox Fuse ByPass Switch part # BX88272 both have a 20 amp max fuse rating. This is mainly due to the gauge of wire that is used in the harness in relation to the distance that the circuit needs to travel. However, I do still have a solution for you that will not require you to physically pull the fuse each and every time and that is the Blue Ox Fuse ByPass High-Amp Fuse Switch part # BX88274 which...

  • Could I use 25 amp fuse in short lead wire which is rated for 20 amp
    The components in the Curt # C93HR Fuse Bypass are only rated for 20 amps. I would not use on a circuit with a higher amp draw. However you can use the Blue Ox # BX88274 bypass rated for 50 amps safely.
