  • Hopkins

Wire your Jeep Wrangler and get the signal lights required for flat towing without having to splice into your wiring with this custom, plug-in harness. Integrated diodes prevent feedback from RV for safe operation.

    • Provides 4-way flat plug at front of towed car to connect to motor home
  • Plugs in quickly and easily - no cutting or splicing of wires
    • Connection points are located behind your vehicle's tail lights

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.

Ordered for a 01 jeep..My tow behind..Got it..installed it..works great to this day..

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.



by:
2004JeepWrangler

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!

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

by:

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 JeepWrangler

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:

This kit was easy to install direction were very straightforward to follow. Made several trips including 4000 mile trip over the last year with no issues with connection.



by:
2004JeepWrangler

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:

Very easy to deal with and fast deliver y!!!!



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:
Jeep

Yes I use it from my motorhome to the jeep I tow and to the trailers.



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!

  • Hopkins or Roadmaster Tow Bar Wiring For 2004 Jeep TJ

  • Recommended Items Needed When Flat-Towing 2002 Jeep Wrangler
    When flat-towing a vehicle like your 2002 Jeep Wrangler behind your motorhome, there are 5 items needed.

Just in case you do not have all of these items I will make some recommendations that will work for you.

  • 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....

  • Could a 2008 Nissan Xterra Flat Tow a 2005 Jeep Wrangler Unlimited
    Flat towing is legal and using a tow bar like the Demco Commander # DM9511012 would be an excellent way to do that. You will need several other components to complete the flat-towing setup beyond just a tow bar. You will need a base plate kit for the 2005 Jeep Wrangler, this will provide the attachment point for the tow bar. For that I recommend the Demco # DM9519045 that pairs up with the Commander tow bar. Next is lighting, for that I would recommend the Hopkins # HM56202. It plugs...

    Thank you for your purchase from etrailer of the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56202. If the signals on your Jeep are not working when connected to your RV you'll want to check a couple things; we know it's on the Jeep side or the harness since your RV works when connected to your boat, so we can narrow it down.
