  • The information that we have is that the Honda Fit Automatic is towable as is for the 2007 to 2011 model years. If you have a 2012 model or If you would like to let me know the year of your Honda Fit, I would be glad to check to see if it is towable or not, or you can check your vehicle owners manual to determine the towability and pre tow procedures for your specific vehicle.

  • Parts Needed to Safely Flat Tow a 2010 Chevrolet Silverado
  • You will need to check your owners manual or with the Chevrolet dealer to see if your 2010 Chevrolet Silverado 4x4 can be flat towed. Some vehicles must be equipped with a transmission lube pump, an axle disconnect, drive line disconnect or free-wheeling hubs before they can be towed. If the correct procedure is not followed it will cause severe damage to the transmission. If you will be able to flat tow your vehicle, you will need a tow bar, base plate kit, safety cables, wiring, and...

  • What is the Correct Diode Kit to Flat Tow a 2007 GMC Sierra 1500 New Body Style
  • I show that for a 2007 GMC Sierra 1500 new body style, you will need to use the Roadmaster 4-diode kit, # RM-154. Your truck has a 2 wire system (combined brake and turn circuit) so additional diodes are not needed. There are diagrams on the product page, below the description, for wiring the diodes, and I have also included the pictures here. If the towing vehicle has a combined brake and turn circuit, you will use the first diagram. If the towing vehicle has separate brake and turn...

  • Tow Bar Wiring to Flat Tow a 2014 Ford Focus Behind a Motor Home
  • Depending on whether the 2015 Coachmen Mirada has a trailer connector, type of connector, or no connector at all is going to determine what type of tow bar wiring you can use. If it has a trailer connector already then the turn signals and brake lights are already combined on the same circuit so it would not matter that the RV has amber turn signals. If it did not have any sort of trailer connector and something had to be hardwired in then the amber turn signals would be a factor in...

  • How Long Does it Take to Install 4-Diode Tow Bar Wiring Kit on a 2014 Jeep Cherokee
  • The trickiest part of installing a diode kit such as # BX8848 is locating and testing the tail light wires and then routing all the wiring. The actual wiring connections shouldn't take long. Assuming you can access the tail light wiring easily and just zip tie the wires under the vehicle from the front to the back installation might take as little as 2 hours if everything goes smoothly. I have included a link to a video showing installation of a similar diode kit on a 2014 Cherokee for you.

Your ability to install the base plates will depend on your mechanical ability. Blue Ox rates the difficulty of install as a 4 out of 10.

  • Blue Ox Tow Bar 4 Diode Kit Installation Details and Troubleshooting for a 2005 Honda CR-V #8848
  • I have linked a video of a very similar product that is being installed on a similar vehicle to yours. Even though the product and the vehicle are different from yours the process of installation is the same. To begin you will need to route the wiring to the rear of the vehicle, this can be done in the internally or externally. If you do route the wiring underneath you Honda CR-V make sure that you avoid moving and heat producing components such as the suspension and the exhaust. Once...

  • 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...

  • How to Install a Diode Kit on a 2014 Jeep Cherokee Latitude
  • LED lights draw much less power than regular bulbs so if you are using a test light, such as # 3808, there might not be enough draw to light up the test light. Using a meter such as # BTMT15 would allow you to test at lower levels of power. I have actually linked a video to the right for a different diode kit that installs in the same way as # BX8848. The video is on a 2014 Jeep Cherokee and it will explain how to install diodes on the vehicle.

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 # BX7365.

  • Does Blue Ox Make Tow Bar Base Plates for the 2013 Nissan Sentra Sedan
  • Blue Ox does now offer a base plate kit for the 2013 Nissan Sentra Sedan. This kit, part # BX1849, fits the Sentra S, SV, SR and SL models. Installation requires temporary removal and trimming of the bumper fascia, minor drilling and temporary removal of the headlights. This baseplate has non-24" spaced attachment tabs.

  • Would the Blue Ox Kargard II Fit a 2015 Jeep Cherokee Trailhawk with Blue Ox Base Plate
  • The Blue Ox base plate kit you would have installed on your 2015 Jeep Cherokee would be the part # BX1136, the part # BX8848 is a diode wiring kit. I checked with Blue Ox and the Kargard II # BX88255 that you referenced isn't compatible with the # BX1136 on your Jeep unless you went and installed an extended shank on your tow bar. Since I don't know what tow bar you have I can't recommend what you need. The Kargard part # BX8870 is compatible with your setup as-is and would not require...

  • Does a Trailer Connector Come with the Blue Ox Tow Bar Wiring Kit part # BX8848
  • You will need to provide the connector needed to connect the Blue Ox Tow Bar Wiring Kit # BX8848 to your tow vehicle. The reason one is not included is so that you can match this kit to what you have on your vehicle. Typically people run a 4-way flat like the part # 18004 or a 4-way round like part # PK11409. I attached an FAQ on how to install this type of wiring kit in a vehicle like yours for you to check out as well.
