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.

  • Parts Needed to Flat Tow 2006 Jeep Grand-Cherokee Behind RV
  • Safe and legal flat towing of a vehicle behind a RV requires a number of components. A tow bar, safety cables, a wiring/lighting kit, base plates and a braking system for the towed car are essential items; a high/low hitch adapter and wiring extension are also often required. The linked article covers each of these in detail and this is a great place to start getting familiar with the requirements. For base plates I recommend the Blue Ox # BX1123 which will fit your Grand Cherokee as...

  • Parts Needed for Flat Towing 2006 Jeep Grand Cherokee
  • If a tow bar like the Roadmaster StowMaster # RM-501 is properly maintained, kept clean and protected during storage periods then it could be perfectly fine. If the tow bar is 10 years old and has never been serviced then a rebuild kit may be in order. For the Stowmaster RM-501 the rebuild kit is part # RM-910003-20. We offer tow bar cover # RM-052-3 for the StowMaster. For a compatible set of base plates I recommend Roadmaster's XL base plate kit # 1427-1. These work with the StowMaster...

  • 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...
