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.

Easy install, works great. Simple route to operate taillights on the toad without draining it’s battery since power comes from the RV.

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!

Easy to install ! About an hour! Used some split flexible wire protection ( not included with purchase) Would recommend a 5ft 4 pole flat trailer connector extension when using a tow bar!

I was looking for a wiring harness to tow my 2000 Jeep Wrangler. I watched a YouTube vidio sponsored by you guys. The video recommended the Hopkins wiring harness. I ordered it, it came with in 3 days as promised and was extremely simple to install!!! Love a company that that delivers what it advertises!!! Thanks again!!!

Instructions were wrong. Wires were too long no tape in box. And I now other than that it’s fine. have to buy an adapter cord to plug it in.

Quality product, purchased a year ago. Installed in my Jeep in roughly 30 min give or take. The directions were easy to read and understand. I highly recommended this product to anyone wanting to wire in taillight for flat tow. You can’t beat the price for a good quality kit like this, a year later and still works flawlessly. This is a true plug and play product. Why pay a shop top $$$ when you can install a hopkins kit in an afternoon. Good job hopkins



by:
2001 Jeep Wrangler

This wiring harness was exactly what I was looking for so that I could tow my jeep behind my RV. No cutting, just plug and play (er I mean tow). There was plenty of extra wiring at the front end so that I could route through the engine bay and mount under the front bumper so it was out of site but easily accessible. Worked perfectly!



by:
2004 Jeep Wrangler

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.



by:
1999 Jeep Wrangler

Looks good, I am waiting for my new front bumper install before I install and test.



by:

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.



by:

We installed the wiring harness and never could get it to work so now we use magnetic lights. It was labor intense too install and a little gun shy to re-order the same product. I am a mechanic and was very disappointed in the light unit.
Thanks, kinda nice to vent!

It all wired up the way the videos showed and worked with no problems. Thank you for posting the videos as the paper instructions were pretty weak.



by:
2003 Jeep Wrangler

From an installation perspective it is plug-and-play and is relatively easy to install. However, the first one I received was defective. There was a problem with the diode pack. The defect caused both lights in the towed vehicle to flash when applying the right signal in the towing vehicle. Kudos to the folks at eTrailer for sending another quickly. I tested the replacement and all functions worked with only one seemingly minor observation, with running lights on either side signal causes a slight dimming pulsation in the other, not-blinking tail light. It shouldn’t be enough to confuse other drivers of your intention. Having to install the harness twice was a huge pain.
My 2003 wrangler brake light function is active with ignition off. This means that the brake lights overrode signals. I with the product info alerted me to this problem. I now need to disable the brake lights in my Jeep when in tow mode. This is probably a common issue. I ordered a relay but have not installed it yet. Having to reinstall the harness again I feel rushed so the relay will have to wait and in the mean time I will pull the fuse when towing.

Here are the parts I recommend picking up to flat tow your 2001 Jeep Wrangler: - etrailer Base Plate Kit # e74FV - etrailer SD Non-Binding Tow Bar # e34ZR - Hopkins Custom Tail Light Wiring Kit # HM56202 - 7-Wire to 6-Wire Flexo-Coil Kit # RM-146-7 - Demco Air Force One Flat Tow Brake System for RVs w/ Air Brakes # DM26VR - High-Low Adapter (see attached article) I like the etrailer base plate kit...

  • Parts Needed To Flat Tow a 1999 Jeep Wrangler TJ Using Blue Ox Tow Bars
    Yes, the Curt Custom Base Plate Kit # C32KR will work with the factory standard bumper on your 1999 Jeep Wrangler TJ. These removable mounts are going to be compatible with Blue Ox tow bars like the Avail Non-Binding Tow Bar # BX7420. The Hopkins Custom Tail Light Wiring Kit # HM56202 will allow you to plug and play your TJ tail lights to work with your motorhome tail lights.

    The Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56202 is a confirmed fit for your 2003 Jeep Wrangler, but in my honest opinion it's an inferior product to a splice in diode kit like the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 which will also come with the adapter cable and 6-way socket. With the Hopkins wiring harness you'll still be doing basically the same amount of labor minus splicing the wires and diodes together and there's a much larger...

  • Troubleshooting Hopkins Towed Vehicle Wiring Installed on a 2005 Jeep Wrangler
    Sounds like you've gotten a decent start on troubleshooting the Hopkins Custom Tail Light Wiring Kit # HM56202 on your 2005 Jeep Wrangler. The first thing I recommend doing is checking the connector on your motorhome side - if there isn't any power present then that would be the issue. If you do end up having power at the motorhome then you'll want to connect to the motorhome and then check the different pins on the connectors themselves to make sure power is getting through to the connectors.

  • Recommended Base Plates Wiring and Supplemental Braking System for 2000 Jeep Wrangler
    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 bumper....

    The Hopkins tow bar wiring harness # HM56202 should be compatible with the Patriot III braking system # BLU37TR 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 your...

  • What Connection Does Hopkins 4-Way HM56202 Make to RV Wiring
    Hey Michael, yes with the Hopkins tow bar lighting kit part # HM56202 the 4-way connector is what would go to the RV's trailer wiring. The Roadmaster Nighthawk part # RM-676 comes with a 4-way round to a 7-way that would plug into your RV so I would replace the 4-way flat with the part # BLU63XR and you'd be fine.

    I am happy to help you find the parts to flat tow your 2004 Jeep Wrangler. The Roadmaster Direct-Connect Base Plate Kit part # RM-521424-5 is a better option for a base plate compared to the Roadmaster # RM-521424-4 that you referenced because the Roadmaster Direct-Connect Base Plate Kit doesn't require you to leave the crossbar of your tow bar on the base plate to use the quick disconnect like the slightly older version.

  • 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. You also may need a way to maintain the Jeep's battery while towing and a high-low adapter to keep the towing setup level. 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.

  • 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 # 119250KIT which is a zero contact kit that uses sensors instead of splices into your 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.

In order to run at highway speeds, I recommend using a tow bar like the Roadmaster Falcon 2 Tow Bar, part # RM-520 and base plate kit # RM-521424-4 which is compatible with OEM double tube bumpers. You will also need a set of safety cables like # RM-643. The Wrangler will also need to be wired for towing. There...
