Ask the Experts about this Blue Ox Tow Bar Wiring

  • Hazards Turn on 2012 Ford Explorer When Headlights on RV are Turned on
    It sounds like your ground could be the problem in this situation. The Ground wire on the Blue Ox Tow Bar Wiring Kit # BX8848 needs to be run to a main Ground or installed directly to a clean, bare metal surface on the chassis of your 2012 Ford Explorer. If you ran the white Ground wire from your 4-Way to the tail lights then you could possibly be getting some residual signal which could be causing your hazard lights to flash. Go ahead and disconnect the Ground wire and Ground it to...

  • No Splice Flat Tow Wiring Solution Recommended for 2019 Jeep Cherokee
    I do have a wiring solution that won't require you to cut or splice into your Jeep's electrical system, however, there isn't a plug and play harness that will allow you to use your Jeep's taillights. Your best option is to go with a set of magnetic lights, like part # MT70097. This light kit simply plugs into your existing 4-Pole Flat trailer connector and features long lasting LED lights that can be easily mounted to any metal surface on your 2019 Jeep Cherokee Overland.

  • Will the Blue Ox Diode Kit 8848 Fit a 2013 Ford C-Max

  • Troubleshooting Diode Trailer Wiring Installed on Vehicle Where Turn Signal Flashes Both Sides
    It sounds like you have the turn signal and running light circuits ran backwards so that when either blinker circuit is activated you end up with both lights flashing. This is because the running lights run to both sides of the vehicle and the stop/turn circuits go to each side specifically.

  • Blue Ox Diode Tail Light Wiring Kit Compatibility with 2008 Ford Taurus X
    The Blue Ox Tow Bar Wiring Kit - 4 Diodes # BX8848 will work well for your 2008 Ford Taurus X. When using the BrakeBuddy # HM39530 you won't need to use a relay or anything to change the functions. It is a simple installation with no additional fuses, bypass systems, or relays needed. You will not need to remove fuses to tow. The only thing you need is a 4-way connector to install on the wiring harness so it can plug into the Brake Buddy. Part # HMC20031 will work fine. It is recommended...

  • Recommended Wiring From Motorhome to RV 4-Pin Trailer Connector
    For a wiring system for your 2018 Nissan Rogue to do what you desire will required the Blue Ox Tow Bar Wiring Kit - 4 Diodes # BX8848 and a 4-way connector on the front of your vehicle. Your 2018 Nissan Rogue is not to be flat towed, but rather towed on a trailer if it is AWD or on a tow dolly if it is FWD. I recommend the Roadmaster Tow Dolly # RM-2050-1 for that and also brake controller # 90195 for the brakes. You will need to hardwire your motorhome wiring for that brake controller...

    The Blue Ox 4-diode tow bar wiring kit # BX8848 that you have installed in your JL Unlimited will not cause issues with the brake lights on the Jeep since it will be in Tow Mode when you are flat towing it. This will allow the motorhome to control the lights. In your 2018 Jeep JL Wrangler Unlimited the Roadmaster BrakeMaster System # RM-9160 will install using a Stop Light Switch kit # RM-751000 which provides a separate "brakes on" signal path back to your motorhome.

  • Can the LED Bulb and Socket Kit # BX88267 be Installed on a 2009 Subaru Forester for Flat Towing
    We do have an LED wiring kit just like the Kit # BX8869 that you referenced. It is found as part # BX88267 on our site. You can use the LED kit if your 2009 Subaru Forester does not have LED tail lights and if each tail light housing has enough room for an extra bulb and socket. It could be that there is no room for an extra bulb and socket which would be why the Roadmaster Kit # RM-152-LED isn't confirmed to fit. If you do have LED tail lights (or you don't have enough room for...

  • Comparing Roadmaster RM-154 and Blue Ox BX8848 Flat Towing Diode Kits
    The Roadmaster hardwired diode kit # RM-154 for flat towing a car will not differ much from a similar kit from another maker, such as Blue Ox kit # BX8848. But since the Roadmaster kit includes a protective wire loom and has been highly-rated by many more users, I would opt for the Roadmaster kit # RM-154. I linked a series of helpful articles concerning tow bar wiring options as well as installation videos for both kits.

  • Recommended Wiring Kit and Other Parts to Flat Tow a 2005 Jeep Wrangler
    Instead of using the # BX8848 wiring kit and adding a connector and umbilical cord between the Wrangler and RV I would use the # RM-15267 kit which includes everything. It will make the installation much easier and have a cleaner look once installed. I've attached an installation video on a 2007 Wrangler Unlimited which will be very similar process to yours. In reference to your other choices, the Blue Ox Alpha Tow Bar # BX7380 is an excellent choice and includes the safety cables....

    To flat-tow your Hyundai Elantra behind your motorhome you will need 5 items. You will need base plates, a tow bar, safety cables, lighting for the Elantra, and most states now require a supplemental brake system. If your Elantra is not a GT the Blue Ox base plates, part # BX2331 would work well. The tow bar that would also work well is the Blue Ox Alpha Tow Bar, part # BX7380. This tow bar is designed with a motor home mount and will work well with the BX2331 base plates. This tow bar...

The installation of the Blue Ox Base Plate # BO94FR and Blue Ox Tow Bar Wiring Kit # BX8848 is likely going to take between 3-4 hours for experienced installers; for those who are doing this for the first time it's likely going to take you twice that.

  • Why is RoadMaster Tail Light Wiring Kit # RM-155 Not Recommended For a 2011 Chevrolet Malibu LT
    Neither one of our manufacturers, RoadMaster or Blue Ox, recommend to use the bulb and socket type of lighting when flat towing a 2011 Chevrolet Mailbu LT. Usually it is because of limited space in the taillight housing that does not allow the bulb and socket to fit properly. We go by what the manufacturers recommend, since they have already done a test fit on the vehicle. The RoadMaster Diode Wiring Kit, part # RM-154, or the Blue Ox Wiring Kit, part # BX8848 is recommended for your...
