Wiring Your Towed Car with Hopkins

Wiring your car for flat towing has never been easier. No more testing wires or splicing into your electrical system. No need to painstakingly position multiple diodes beneath your vehicle. No worries about voiding your warranty. With this custom-fit towed vehicle wiring kit from Hopkins, all you have to do is plug the harness into your vehicle's existing wiring, which is located behind your car's tail light assemblies. No cutting, tapping, or splicing is required.


After plugging in the wiring harness, use the included bracket to mount the 4-way flat connector at the front of your towed car. An extension loop (sold separately) is required to connect your towed car to your RV.


Separate vs. Combined Lighting Systems

Some automobiles operate on a 3-wire system, wherein the brake signal and the turn signals travel along different wires to illuminate different lights. (Typically, these vehicles have amber turn signals.) This is referred to as a "separate lighting system." When you hook up for flat towing using this harness, your towed car's lighting system will operate in a combined fashion regardless of whether it typically has combined or separate lighting. This means that the brake and turn signals sent by your RV to your towed car will be carried on a single wire. As a result, your car's brake lights will do the flashing for the turn signals. Your vehicle will still function as designed when not hooked up to your RV.


Do You Need a Brake Light Relay?

Because this harness wires your vehicle as a combined system, a brake light relay (RM-88400 - sold separately) may be required if you use a supplemental braking system with your towing setup. A supplemental braking system depresses the brake pedal in your towed car every time you apply the brakes in your RV. So, if your towed car's brake lights illuminate when the brake pedal is pressed and the engine is off - as is the case when towing - then you need to install a relay to ensure that the lights on your towed car always act in accordance with the signals sent by your RV via the wiring harness. Without a relay, the brake signal from your towed car will override the turn signal sent by your RV when you slow down to make turns, creating a potential hazard.

Do you have a question about this Tow Bar Wiring?


  • Will the Roadmaster Even Brake # RM-9400 Work on a 2008 GMC Canyon
  • The Roadmaster Even Brake Portable Braking System, # RM-9400, will work on your 2008 GMC Canyon as long as it does not have an active power assist braking system. The need for the Brake Light Relay, # RM-88400, will depend on the tail light wiring harness you choose to use. Since your GMC Canyon has a separate tail light system, meaning the turn signal and brake lights use separate bulbs in the tail light assembly, you will only need the brake light relay if you use the Hopkins Wiring...

  • Installation of Flat Towing Wiring Harness HM56109 in 2011 GMC Canyon
  • Hopkins Plug-N-Tow (R) Vehicle Wiring Harness # 41165 includes a converter module that processes the lighting signals from your 2011 GMC Canyon before sending them on to your trailer. 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. You will also want to check your GMC owner's manual for any instructions regarding preparing the vehicle for flat towing....

  • Recommendations For Parts Needed to Tow 2012 GMC Canyon With Towbar Blackhawk 2 Behind Motorhome
  • When towing a vehicle with a motorhome there are five components needed: baseplates for the towed vehicle, towbar, safety cables/chains, lighting system, and supplemental braking system. Starting with the baseplate, as long as your 2012 GMC Canyon is not the Z71 or Xtreme model, then RoadMaster XL Base Plate # 3122-1 will fit your truck. If your 2012 Canyon is the Z71 model then RoadMaster XL # 3164-1 is the correct baseplate kit for your truck. Both kits have removable arms and will...

  • Tow Bar Lighting Recommendation for a 2005 Chevy Colorado
  • Trailer wiring cannot be used in reverse to power the taillights it is connected to for tow bar lighting. You will need to go with a tow bar lighting like the part # HM56109. This will plug inline with your current taillight harnesses (most likely like your current trailer wiring), and will work to power the taillights while your 2005 Chevy Colorado is being flat towed. I attached a help article on flat towing for you to check out as well.
