  • Extending a Wire on the 4 Pole to 6 Pole Adapter
  • I would not recommend connecting the white wire to the brown wire, because the white wire is your ground connection. If you need more wiring just splice the brown wire and simply run a new 10 gauge wire # 10-1-1 to resolve this issue. The Hopkins Deluxe Trailer Wiring Installation Kit # HM51020 will allow you to make all the connections in this process easier.

  • You will need the Universal Wiring Harness # RED69FR to install the Redarc Tow-Pro Liberty Brake Controller # RED24FR into your 2016 GMC Canyon. This will allow you to splice into the wiring that is on your Canyon as there is not a plug and play style connector and the wires are just terminated under the lower side panel fascia on your Canyon. I have included a video of an installation of a different brake controller on 2017 Chevrolet Colorado but the wiring will be similar. Once you...

  • Tail Light Wiring Converter to Join European Motorcycle and U.S. Trailer Wiring Formats
  • As you noted, trailers made for the U.S. use a combined wiring scheme for their lighting. Stop and turn signals for each side of the trailer are combined into one circuit and one wire. European wiring is different; it has all separate circuits. This is why there are no simple adapters that can join the two wiring standards and why converters are needed. Since your German-made Rewaco trike would be wired to the European standard you will need a converter to make it compatible with your...

  • Isolating Power for a 5-Wire Motorcycle Trailer Harness and a 5-Wire Motorcycle Trailer
  • There is a way to isolate the power draw on a 5 wire to 5 wire setup, but it would require a few parts and some wiring work. All of the isolated power trailer converters convert a 5-wire vehicle to a more standard 4-wire system for automotive use trailers, but as you are aware, motorcycle trailers are built as 5-wire systems to match the bike. You would use part # C59496 on the bike. This part has 5 wire leads to connect ground and the different light functions. The 6th wire is the battery...

  • 4-Way Connector Needed to Replace 4-Way on Trailer with 6 Wires
  • Since you have six wires it sounds to me like you have a double ground and a left and a right side tail light wire. If this is the case you could use a wishbone harness like the 20 ft. Wishbone 4-Way Trailer Wiring Harness with 30" Ground Wire, # A20WB, as a replacement because it has the separate left and right side tail light wires. I recommend using a spare car battery to assist with testing the trailer wires for function. You will just need to ground the negative terminal of the battery...

  • Parts Needed For 1999 Ford Taurus Wagon With Separate Stop and Turn Lights to Tow Trailer With 4-Way

You do not need to change the wiring on your trailer to match your vehicle. There is an easier solution for getting the vehicle and the trailer connected. You will want to use the Draw-Tite Wring Harness, part # 119178KIT, on your Taurus to get a 4-Way connector. This wiring harness will use a...

  • Parts Needed for Custom Wiring a Trailer For Separate Turn and Brake Lighting
  • In order to have separate turn and brake lights on your trailer, I strongly recommend using a 2-wire to 3-wire converter, like the Tow Ready # 118158 on the trailer. This will allow you to have 4-way connectors on both the vehicle and the trailer. The 4-way connectors are much more common than 5-way connectors, and will allow to you tow other things with your vehicle, or tow your trailer with other vehicles, without the need for an adapter. This converter box is not designed to be exposed...

The wiring configuration will be as follows: Cycle LEFT turn goes to yellow wire Cycle RIGHT turn goes to green wire Cycle BRAKE goes...

  • Is a Brake Controller Plug-In Wiring Adapter Available for a 2014 Thor Palazzo Motorhome
  • I wish I had better news, but Tekonsha does not offer a plug-in wiring adapter for your 2014 Thor Palazzo motorhome. We have run into this question before and apparently Freightliner built this plug into some of their Class A motorhomes, but a wiring adapter was not designed to work with it. Your best option would be to use the universal harness that comes with the Prodigy P2 and tap into the wires just behind the plug. If you need a new harness, you can use part # 7894. We do not have...
