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.

Do You Need a Brake Light Relay?

Because your vehicle has a combined lighting system - wherein the brake signals and the turn signals are carried on a single wire - 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.

  • Can Hopkins Custom Tail Light Wiring be Used along with a T-One Harness on a 2010 Chevy Malibu
    The Hopkins # HM56106 and the # 118450 can indeed be used together without conflict, but the only problem you might have is the limited amount of space available between the back of the tail light and the vehicle body. Some of your connections might need to be pushed through the grommet into the trunk interior in order to get the tail light assembly put back into place. The Hopkins flat towing wiring harness should be plugged into the rear of the taillight assembly, the # 118450 connected...

  • Flat Towing Lighting Solution for a 2012 Buick Enclave
    The bulb and socket kit, # RM-155, does fit the 2012 Buick Enclave. Wire length could be an issue on any vehicle. It all depends on how the wires are routed under the vehicle. Normally, unless it is a truck, the wire length is more than enough. Bulb brightness can be affected by several factors including getting the proper voltage back from the RV. The bulbs that are used are automotive bulbs (incandescents) which are not as bright compared to LEDs. What I recommend is to use the custom...

  • Recommended Flat Towing System for 2010 Buick Enclave For Easy Install

  • Parts Needed to Flat Tow 2012 or 2013 Buick Enclave
    According to the online version of the owner's manual for the 2012 and 2013 Buick Enclave, it can indeed be flat towed behind an RV with all 4 wheels on the ground. I highly recommend verifying this information in your copy of the manual as well as reading through any guidelines or restrictions when it comes to flat towing. In the owner's manual this section is listed under "Recreational Vehicle Towing". In order to tow your Buick Enclave you will need a base plate kit, a tow bar, safety...

  • Base Plate and Tow Bar Recommendation for a 2011 Chevrolet Malibu
    Of the base plate options that fit your 2011 Chevrolet Malibu I recommend the Roadmaster EZ base plate kit because the installation will be a little easier and will not require you to remove and reinstall the headlights. The EZ base plates are compatible with all Roadmaster tow bars. The Falcon 2 Tow Bar, # RM-520, is our most popular Roadmaster tow bar. Along with a base plate kit and tow bar, you need safety cables, tow bar wiring and a supplemental braking system to complete your flat...

  • Parts Needed to Flat Tow a 2008 Chevrolet Malibu with a StowMaster Tow Bar
    To flat tow your 2008 Chevy Malibu with a Roadmaster StowMaster tow bar, you will first want to add a set of base plates. Since you will be using a StowMaster tow bar, I recommend installing the Roadmaster EZ Base Plate Kit, # 523145-5. The Quick Disconnects, # RM-222, are required for the StowMaster tow bar to connect to the base plate. If your StowMaster tow bar does not have the vehicle side Quick Disconnects, then you will need those as well. I also recommend checking your owners manual...
