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.

I just finished installing this harness on my 2003 Wrangler. As any wiring on a Jeep, it was uncomfortable and tight to access the wiring. This is normal. The installation sheet instructions were inaccurate for my model, I have a career in automotive, so it was no problem for me. I installed this for flat towing of my Jeep. I ran the harness over the fuel tank and down the drivers side undercarriage, that is where the main harness and brake lines run. 848465

Excellent product, looks to be made of quality components. The install was easy, everything fit the way it should on my 2006 Wrangler. HOWEVER, the installation instructions in the package were completely wrong and useless. Instead see the installation video on their website which is correct and clearly walks you through the process. 672753

Good product. Install directions should include which plug in at each taillight should be used if you already have trailer hitch plug in wiring installed. Had to go to Youtube and find a video that talked about the correct colored wire you should connect to. Other than that, install went well. 657781

This was a breeze to install!! About 30 min and I had working lights on my Jeep and was ready to hook it up behind my motorhome. Price was great too. Stopped at my local RV dealer and he said he could get me a wiring kit for $250! Saw this one online for $50 bucks and took a chance. Sure glad I did! Disconnect a couple of plugs, plug in new harness, route the wires to the front and BOOM! Ready for the trip! Thanks guys! 558914

I open the package and all looks correct, have not yet installed on Jeep to see if the light connectors are the same. The only issue I have is I wish that the flat 4 pin connector could come in the 4 pin round connector. Once I install and make sure all works fine, I will be changing out the flat connector to the round connector. Again Great service from Etrailer!! 554322

Ask the Experts about this Hopkins Tow Bar Wiring

  • Can Hopkins HM56202 be Wired into 6-Way Connector on Front of Towed Vehicle
    Absolutely! We actually recommend doing this exact install a lot of the time. Using a 6-way, like part # PK12720 for an example, at the vehicle's front allows you to install additional wiring for a braking system or charge line but doing it this way makes it an easier install because the Hopkins # HM56202 is the easiest to install harness for your 2004 Jeep.

  • Does Hopkins Tow Bar Lighting Kit # HM56202 Fit 2004 Jeep Wrangler Taillights
    The Hopkins Custom Tail Light Wiring Kit # HM56202 that you referenced was designed to fit your 2004 Jeep Wrangler's taillight configuration of separate turn signals from stop signals so it will fit and function really well. It combines the circuits onto one combined circuit.

  • Wiring for Flat Towing 2006 Jeep Wrangler
    I assume you would like to flat tow your 2006 Jeep Wrangler and have 4-Pole Flat Trailer Connector # 32625. If this is the case you can use Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56202; the Hopkins kit for towed vehicles plugs into your Jeep's tail light housing assemblies while the connector plugs in behind the rear tire mud flap on the driver's side.

With your vehicle key in the off position press the brake pedal. If the brake lights come on then you need the relay. If not you don't need it.

    The Hopkins Custom Tail Light Wiring Kit for Towed Vehicles part # HM56202 will not work on your 1997 Jeep Wrangler TJ because Jeep changed the pinouts on the tail lights between the 1997 and 1998 model years. Therefore, it will plug into the connectors behind the tail light housing but will not function properly. There is not another plug and play flat-tow wiring harness for your Jeep so I recommend using the Roadmaster Tail Light Wiring Kit with Bulbs part # RM-155 as it will not...

    The Hopkins tow bar wiring harness # HM56202 should be compatible with the Patriot II braking system # BRK2016 for your 2000 Jeep Wrangler. I do recommend using the brake lite relay # RM-88400 to ensure that the Jeep brake lights do not override the turn signal sent by the towing vehicle. Installation is easy. The wiring harness will just plug in line with the vehicle tail light wiring. I have included a link to instructions for another harness that fits and installs the same way on...

  • Troubleshooting Jeep Lights Not Working with Flat Tow Harness
    Since your Jeep lights work normally when it is not connected to your RV your harness # HM56202 is probably connected properly.

You can use a circuit tester like # PTW2992 on the contacts while a helper activates the brake, turn and running lights on the coach. Please refer to the linked article on wiring to see which contacts handle which signals on the various types of RV connectors. If...

  • With Hopkins Tow Bar Wiring Plugged In 1998 Jeep Wrangler Right Turn Signal Does Not Work
    To determine where the problem is I ask you to disconnect the Hopkins harness # HM56202 from the passenger's side and plug the vehicle tail light wiring in like normal. If the right turn signal still does not work then the bulb could have blown or a fuse may need to be replaced. If it does work then check the connectors on the Hopkins harness to see if there are any broken or bent pins or any corrosion anywhere on its or the vehicle's connectors. If that is not the issue then there...

    You should be able to tow the Wrangler, but as a first step you'll want to look in the owner's manual in the Towing or Recreational Towing section for any procedures or recommendations from Jeep. My research indicates that your Wrangler can be flat towed without modification, but I'd urge you to confirm this for yourself. If you find your Wrangler can be towed on all 4 wheels, you'll need a # BX1120 base plate if your Jeep has the OEM double tube bumper or # BX1118 for the U-channel...

  • Trailer Wiring Recommendation for 2000 Jeep Wrangler with Tow Bar Wiring Already Installed
    Since you can't install custom fit trailer wiring and tow bar wiring at the same time that both use the taillight connectors as how they wire in you'll need to hardwire in a universal trailer wiring kit like the # 119190KIT or if you want a zero contact kit that uses sensors instead of splices you'd want the part # 119250KIT.

  • Best Parts to Flat Tow a Jeep Wrangler TJ with D-Ring Adapters
    Towing your Jeep Wrangler TJ behind your motorhome requires a tow bar, a kit to connect the tow bar to the Jeep, a lighting solution, and a braking system.

One of the best tow bars on the market is the Roadmaster Nighthawk All Terrain, part # RM-676. It's a non-binding tow bar that makes it easier to connect on unlevel ground.
