Roadmaster Flat Tow Wiring Harness - RM-76517

  • Fuse Bypass
  • Bypasses Vehicle Wiring
  • Engine Compartment
  • Roadmaster
  • Custom
  • FMX Fuse

We highly recommend this fuse bypass switch if you need to deactivate a fuse when you flat tow. It's a huge pain to pull the fuse by hand every time, and you risk losing or damaging it. With this kit, you just have to flip a switch.


Features:

  • Keeps battery from draining with the flip of a switch
    • Deactivates the fuse while flat towing
  • Saves you the hassle of removing the fuse by hand
  • Stores fuse so that you won't lose or damage it
  • Mounts in dashboard and connects to fuse box
  • Includes fuse controller, wiring harnesses, ring terminals, spade connectors, and installation hardware
    • Fuse controller allows the high current fuse to be turned on/off without sending high current through the switch
  • Application: 50-amp FMX fuse
  • Made in the USA


Note: Consult your owner's manual to determine which fuse to pull.


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 popping the hood and fishing a tiny fuse out of your battery compartment 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 headache.


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.

I ordered one of these and had it installed by one of the providers suggested by etrailer.com. It didn't work but I can't get a refund since too much time had passed between the time that I ordered and the time I had it installed. I could order a second one though and try to replace possibly defective parts in the first and could return the second for a refund. However, the second one doesn't work either. The tech talked with Roadmaster and they were stumped as to the issue too. Roadmaster is going to send yet a third bypass switch directly to shop to see if this one will work. Basically, I am out of a whole bunch of money and still do not have a fuse bypass. I should have just kept pulling the fuse manually as I had been doing!

Nothing buy trouble. Poor engineering on my 2013 Equinox model. Might be fine for others. It did not isolate the parasitic power drain, even with a 12 volt power supply from the RV.

Hi Scott, the FuseMaster will only remove the need to unplug and reinsert your fuse for flat towing. If you have a 4-cylinder, you will need to leave fuse DLIS #32 intact and pull the ABS module fuse located under the hood. Please note, due to manufacturing variances some 4-cylinder models may label the ABS module fuse as #15 or #16. You will also need to install a charge wire kit, # RM-156-25. This information is current as of November 20, 2017. Contact the vehicle manufacturer for further updates.



by:

Roadmaster made sure I had the right part for my car , they also out fitted many years ago my 2013 Equinox with everything I needed for towing behind my RV. Thanks Roadmaster



by:

As always great help fast delivery and a wonderful staff!

Good instructions and easy to instal tnx to Lori AB for putting my order together



by:

It would be nice if you could send directions in written form,I have not used it due to lack of written directions,



by:

The product was ok other than the switch. It is hard to tell if it is on or off. I wound up just using the fuse holder as it is easier to pull the fuse out. Other than that was great service.



by:

Ordered and install base plate over a year ago and finally got to use it a couple of weeks ago because motorhome was in shop waiting on parts. Pandemic and supply chain issues. Anyway, the base plate and accessories work great. Dinghy tracks well. Hardly know it’s back there.



by:

Installed as per installation video and all went great.

Towed over 7000km last year with no problems. It is great to not have to pull fuses anymore.

Does what it is intended to do. Took a little time to install but it came with all the instructions I required, and it all looks and works great!



by:

The connections at the fuse panel were difficult to tell which was hot.

The instructions say the thick black wire is the cold side and the large red wire is the hot.

Easy enough to install on 2010 Chevy Equinox LT. Very clear directions and video was very helpful. (Thanks etrailer for all the good videos) Have not towed yet but seems to be exactly what I need. Much better than pulling fuses.



by:

This has saved us so much time! Popping the hood and physically pulling the fuses on our vehicle every time we stop gets old quickly. This system was easy to install with the step-by-step video and works flawlessly.



by:

The best customer service from Melissa, and her manager. Delivery and follow up was the best as always. Will continue to purchase from etrailer in the future.This is the way all companies should conduct business.



by:

Good quality, complete kit, fairly easy to install once you watch the videos



by:

Better than opening the hood every time we tow.



by:

Works great and allows me to tow with vehicle stability turned on; no more death wobble! Installation instructions were clear and it fit perfectly.



by:

Right part at the right price.Fast and helpful employees.

Wire kit has been working good for a year now.

  • Can a 2017 Chevrolet Equinox Front Wheel Drive Be Flat Towed With all 4 Wheels On The Ground?
    Yes, your 2017 Chevrolet Equinox FWD can be flat towed with all 4 wheels on the ground. Do understand that you will need to run your Equinox for 5 minutes every time you stop for gas to properly lubricate your transmission and before towing. A better option may be to use a Dolly # DM9713093 so you will not have to let your engine run before towing or during stops. If you prefer to flat tow you will need the following components.

  • Fuse Bypasses Needed To Flat Tow A 2015 Buick Enclave
    Hey Steven, To bypass the 15 amp ECM and Onstar fuses you can use the # RM76514 and for the 50 amp BATT1 fuse you can use the # RM-76517. These both come with switches to activate/deactivate the fuses. You'll likely need to splice in some extra wires to run them up to the dash for easier access.

    You will need to use two different fuse bypass kits; the Roadmaster FuseMaster # RM76514 has two fuse holders for the both the ONSTAR and ECM fuse and the Roadmaster FuseMaster # RM-76517 for the BATT1 fuse. These fuses do more than just drain the battery and would still need to be removed regardless if you installed the Roadmaster Battery Charge Line Kit # RM-156-25.
