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.

2008 Jeep Grand Cherokee

I purchased this wiring for my 08 Jeep Grand Cherokee, to flat tow behind my motor home. It works exactly as advertised, and for the most part it was easy to install. My only complaint is that the wires that run from the left tail light to the right side were way too short. I had to add about 3 ft of wire to make it work. But once that was complete it was a pretty simple installation. It's very clean! I mounted the plug under the bumper and behind the license plate so it's completely unnoticeable. Then I purchased a 6 ft extension to go from the plug to the motor home. I would recommend this kit for it's simplicity. And it uses all factory style connectors, so you don't have to cut any of the factory wiring in the vehicle.

The package had everything I needed to convert my 2008 Jeep Grand Cherokee to enable me to flat tow it and have running, brake and signal lights. I had to cut the flat 4 way plug off and attach it to my 6-way plug that I already had on my tow bar. Overall it was a nice install.

Easy to install and works great.

  • Recommended Tow Bar Wiring For 2007 Jeep Grand Cherokee
    I called my contact at Hopkins and asked about your 2007 Jeep Grand Cherokee. They told me that you can look on the door jamb of your Jeep for a sticker that should have the manufacture date. If your Jeep was built from January to mid June then it is the early year model and the correct harness is part # HM56206. If you find that it was built after mid-year then the right harness is part # HM56207. If using a supplemental brake system a brake light relay like part # RM-88400 is required. Another...

  • What do I Need to flat Tow a 2011 to 2013 Jeep Grand Cherokee Behind a Motorhome
    To flat tow a 2011 to 2013 Jeep Grand Cherokee there are 5 major components needed: base plates, tow bar, safety cables, lighting, and supplemental braking. The base plates are what attach to the front of the Jeep and provide a safe and proper attachment point for the tow bar. For the 2011 to 2013 Grand Cherokee I recommend Roadmaster EZ5 base plates # RM-521440-5. These base plates feature removable arms that, when removed, makes the base plates almost invisible. I have linked a video...

  • Best Flat Towing Setup Recommendation for a 2007 Jeep Grand Cherokee
    First let's start with a base plate kit. For that I would recommend the Roadmaster Base Plate # 1427-1. This is the most popular option we have for your vehicle and I attached an install video for you to check out as well. In addition to the base plates, you will also need a compatible tow bar, safety cables, lighting, and supplemental braking to flat tow your vehicle. The most popular compatible tow bar is the Falcon 2, # RM-520. For safety cables you can use # RM-643. The coiled design...
