Expert Answers about Flat Tow Wiring Harness


  • Will a Flat-Tow Wiring Harness for a 2020 Jeep Wrangler Unlimited Work With Trailer Tow Harness
  • In order to activate the tail lights on a 2020 Jeep Wrangler Unlimited from the motorhome you will need a flat-tow wiring harness, the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit part # RM-15267 is our best and most popular option for this. It does require splicing but that is the only option available. It would work just fine with an existing trailer tow wiring harness. The Hopkins Plug-In Simple Vehicle Wiring Harness part # 42615 is not a fit for a 2020 Jeep Wrangler Unlimited...

  • Can Trailer Wiring for 2019 Jeep Cherokee Be Connected to Flat Tow Wiring Harness
  • I'd be interested to know what exact Curt wiring harness you installed for flat towing your 2019 Jeep Cherokee since flat towing harnesses are designed to receive power while towing harnesses are designed to send power - something like what you described doesn't exist as far as I know. Now what you CAN do is install the Curt T-Connector Vehicle Wiring Harness # C56406 in addition to a flat towing harness. This will just tee in behind the tail lights like your flat towing wiring might have...

  • Can 4-Pole Trailer Wiring Harness and Flat Towing Harness Be Used at Same Time on 2012 Jeep Wrangler
  • According to the folks at Hopkins, you can indeed use the # HM42635 trailer wiring harness and their # HM56200 flat towing wiring harness at the same time. I've linked to the installation video for the flat towing harness and instruction sheets for both parts. I've also linked to an article that runs through all the products needed to safely flat tow your Wrangler.

  • Can Flat Tow Wiring Harness for 2011 Honda CR-V be Connected to Trailer Wiring Harness
  • That is an excellent question. The difference between a trailer wiring harness like the Curt # C55106 and a flat tow wiring harness like the Hopkins # HM56300 (similar to the Curt you mentioned) for your 2011 Honda CR-V is that the trailer wiring harness sends power to trailer lights while the flat tow harness receives power from your motorhome. So even though they connect to the same circuits, they serve different purposes so they aren't interchangeable. For a complete flat towing setup...

  • Will Trailer Tow Wiring Harness Work As Flat-Tow Wiring Harness for 2003 Honda Accord
  • It sounds like you are looking for a flat-tow wiring harness for a 2003 Honda Accord and if that is the case we have plenty of options but trailer tow wiring harnesses like the Curt T-Connector Vehicle Wiring Harness won't work. Instead, I recommend the Roadmaster Universal Hy-Power Diode Wiring Kit part # RM-154. There are unfortunately no plug-in-play options. If you already have a trailer wiring harness installed, this won't cause any issues for the flat-tow wiring harness but it won't...

The flat-tow wiring harness will take input from the motorhome's lighting signals and then apply these to the towed vehicle.The flat-tow wiring harness is going to be composed of two components, the umbilical which bridges the gap between the tow vehicle/toad and the trailer side flat-tow wiring harness which is what gets spliced...

  • Is the Mopar Flat-Tow Wiring Harness Required for a 2015 Jeep Cherokee Trailhawk
  • I checked the owner's manual for a 2015 Jeep Cherokee, it does show that the Mopar Flat-Tow Wiring Harness is required. In addition to this, you'll need a base plate kit, tow bar, safety cables, flat-tow wiring harness (different than the Mopar Flat-Tow Wiring Harness), and a supplemental braking system. I have attached a list of these components for you below. Roadmaster Direct-Connect Base Plate Kit part # RM-521446-5 Roadmaster Nighthawk All Terrain, Non-Binding Tow Bar part # RM-676 Hopkins...

  • Can Flat Towing Wiring Harness Be Used With Trailer Towing Harness on 2014 Chevy Equinox
  • Although your existing 4-pole can't be used for flat towing the vehicle, you can indeed still add a plug and play wiring harness for flat towing. The trailer wiring harness would connect inline between the vehicle's wiring harness and the taillight assembly. The flat towing harness would daisy chain into that connection. I'd recommend using the Hopkins # HM56108. Since removing a fuse is necessary to prevent the vehicle's battery from being drained when being towed, you can use a fuse...

  • Can You Install Both Trailer and Flat-Tow Wiring on a Jeep Wrangler
  • Yes, you can install a flat-tow wiring harness along with a trailer tow wiring harness on a Jeep Wrangler without issue. For a trailer wiring harness I recommend the T-One Vehicle Wiring Harness part # 118786 and for the flat-tow wiring harness I recommend the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit part # RM-15267. Please note, the T-One Vehicle Wiring Harness is for 2018+ models only but the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit works will all years.

  • Recommended Flat-Tow Wiring Harness for a 2000 Jeep Wrangler
  • I do have a plug-in flat tow wiring harness available for your 2000 Jeep Wrangler but the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles part # HM56200 that you referenced is not correct. Instead, you will want to use the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles part # HM56202 which is a confirmed fit for your 2000 Jeep Wrangler. This harness like the above is a plug and play option that will not require any splicing. I have attached a review video of the harness...

  • Trailer Hitch Receiver & Wiring For 2021 Jeep Grand Cherokee Set up For Flat Towing
  • Hello Phillip, Yes, you can add a trailer hitch and wiring to your 2021 Jeep Grand Cherokee that is already set up for flat towing. The procedure will be exactly the same installing a hitch, it's just the wiring that might be a bit different. If your Grand Cherokee has a flat tow wiring harness that plugs into your Jeep's lights, the trailer wiring harness will tee in. If your flat tow harness splices in, then the installation of the trailer wiring harness won't be any different at all....

  • Recommended Plug-In Flat-Tow Wiring Harness for a 2001 Jeep Grand Cherokee
  • I have some great flat-tow wiring harness options for a 2001 Jeep Grand Cherokee. That said, the trailer wiring harnesses which is what you were looking at are different than the flat-tow wiring harness options which is what you need. If you want the signals sent through the taillight then I recommend using the Roadmaster Universal Hy-Power Diode Wiring Kit part # RM-154. There won't be any plug-in-play options though.

  • Custom Flat Towing Wiring Harness for a 2007 Jeep Liberty
  • Yes, there is a custom flat towing wiring harness available for your 2007 Jeep Liberty. It is # HM56203. If you are also using a supplemental braking system when flat towing the Jeep, which is required in most states, you will also need to use a brake light relay, # RM-88400. The Even Brake system, # RM-9400, includes the relay. I have included a couple of helpful links to our articles on flat towing for you.

  • Can Towing and Flat Towing Harness be Combined on 2018 Ford Focus?
  • No, you would not be able to somehow combine the two wiring harnesses to use with your 2018 Ford Focus, they are for separate applications and need to be treated as such. Wiring Harness # 118674 will be what you need to install for a 4-flat to tow with hitch # C11158 and Roadmaster Wiring Kit # RM-154 should be installed for flat towing, but there cannot and should not be a combination of the two.

This module will be damaged if fed lighting signals from a motorhome. Before you flat tow the Canyon unplug the trailer harness # 41165 and plug in the Flat Towing harness # HM56109.

  • 2023 Ford Bronco Wildtrak Trailer Hitch and Wiring Recommendations
  • Since flat tow wiring is designed to receive a signal and trailer wiring harnesses are designed to send a signal you will need a second wiring harness on your 2023 Ford Bronco Wildtrak, but it will be a style that tees in so it will fit with the Curt flat tow wiring. Here are the parts I recommend installing on your Bronco: - Draw-Tite Max-Frame Trailer Hitch Receiver # DT37GR - Curt Wiring # C42WR (for 4-Way flat) OR Tekonsha Wiring # TK55VR (for 7-Way) - Wiring Bracket # BK4F (for...
