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.

by:
2004 Jeep Wrangler

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!



by:

Easy plug and play. I cut the 4pin connector off and wired a 6 pin socket with battery caharge line to be compatible with my tow vehicle and other TOADS

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:
Jeep Wrangler

This product does exactly want its description states. It took me 2 hours...most of the time was spent trying to fish out my connectors on my TJ Wrangler especially the right was difficult...I'm still sporting a few cuts on my hand and forearm cuz the metal behind the right tail light is sharp. My local RV repair/installer wanted about 500 bucks to do want this part does. Now I'm legal to tow my jeep to Moab with my Tundra. When it gets warmer I will insulate the wires a bit more.
Hoped this helped.

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:
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.

I am very satisfied

1999 Jeep TJ

After one year on the vehicle and also installing new LED lights, the wiring kit is still working. I love not having to add extra lights for towing.



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.

    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 is...

This kit was custom made to fit your vehicle and will not require any hardwiring or drilling of the light assemblies to install.

    The issues you're seeing won't be caused by not adding a relay to the wiring when you installed the # HM56202 and Brake Buddy Stealth # HM39530 and since you've already checked all of your ground wires I recommend moving on the the # HM56202 itself.

  • 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.
