CURT Flat Tow Wiring Harness - C96JR

  • Wiring Harness
  • Plugs into Vehicle Wiring
  • 4 Flat
  • CURT
  • Custom Fit

Plug-and-play custom harness gets turn and brake signals on your towed car with no hardwiring or splicing, and no effect on your warranty. The built-in diodes protect your car from electrical feedback.


Features:

  • Allows your RV's tail, brake, and turn signals to display on your car's tail lights
  • Plugs right into car's connection points - no cutting or splicing
    • Custom designed for your vehicle
    • No effect on your warranty
  • Prevents feedback that can damage your vehicle's electrical components with diodes
  • Provides 4-way flat plug at front of towed car
    • Requires additional harness to connect to motorhome - sold separately
  • Includes wiring harness, mounting bracket, and installation hardware


Specs:

  • Max amperage: 7.5 amps per circuit
  • Limited 1-year warranty


Notes:

  • A brake light relay (RM-88400 - sold separately) may be required if used with a flat tow brake system. (See below.)
  • A wiring converter (118158 - sold separately) and 2 additional diodes will be needed to retain separate turn and brake signals. (See below.)


Combined Lighting System vs Separate Lighting System

Combined vs Seperate Lighting System

A combined lighting system, or 2-wire system, uses the same light bulb to signal both braking and turning. (In other words, the car signals a turn by flashing the brake light.)


A separate lighting system, or 3-wire system, has the brake signal and the turn signal light up independently of each other. Typically, the turn signal is amber.


To keep the separate lighting system on your car functioning properly while you're flat towing, add a wiring converter (118158 - sold separately) and 2 additional diodes.


Do I Need a Brake Light Relay?

If the engine is off and your car's brake lights illuminate when you press the brake pedal, you need to install a brake light relay (RM-88400 - sold separately) with this kit. Without a relay, your car's brake signal will override the turn signal sent by the RV when you are slowing down to make a turn, creating a potentially dangerous situation. Other drivers will see that you're slowing down, but not that you're making a turn. With a brake light relay, you can signal both and travel safely.

The wiring kit is SHORT!!
It lacks 3’
in making it to the baseplate.
I was concerned when I received it and noticed the box indicated it was for a Jeep JL which is a bit shorter than a gladiator.
The fix is to splice the harness, what a horrible situation!



by:

Simple and easy purchase process. The installation of the Curt custom tail light wiring kit was almost as simple and easy as the purchase. etrailer is great!

This wiring harness is still going strong! I haven’t had any issues with my lights not working while towing or the vehicle lights when not towing.



by:
2025 Jeep Gladiator

I liked the quick connect tail light plugs. I was very disappointed that the wire harness going from the back of my gladiator was too short. I took careful measures to make certain not to route the wire poorly so I wouldn’t have any length issues. Unfortunately that didn’t work out. I ended up having to splice the 4 way to reach the middle of my front bumper so I could complete the job. That harness needs to be 4 feet longer for gladiators. Buyers this is a nice harness but beware it poses problems with length. There is no way to properly route this harness without adding to it’s overall length.



by:

This kit does a good job. Wish it had a protective sheathing wrapped around it for added protection. Was just long enough to reach the front of our jeep gladiator.

The product was exactly as advertised. It was processed in a timely manner. However due delays in shipping by usps. It took 13 days to arrive. The initial estimate was 5 to 7 days . I was forced to miss a trip due to the delay. When I contacted etrailer and asked for another item to be shipped by a ups I was informed I would have to wait at least 14 business days. I am a frequent customer but this experience has me rethinking using etrailer in the future due the customer service unwilling to flex a little



by:

Product was excellent as advertised however installation instructions could be better with clearer pictures. Routing of wiring at rear of vehicle has many options however one route gives the safest and easiest to install.

Wiring harness worked great easy to hook up. I ran the entire harness in plastic wire shield snd then pulled it through inside frame from back to front on drivers side of jeep to ensure it wouldn’t get ripped off.

Although the package was missing a portion etrailer immediately agreed to expedite the part to me. Great customer service, as is the norm for them. Would be 5 stars if all parts came in same shipment. Great company!

Very easy to install and very well made. I'll recommend it to others

Great wiring harness, plug and play, easy to install and all the lengths fit my Jeep as they should.
The only problem is the description stated there is a plug in the middle for use with a trailer hook up. They didn't say the plug was not a flat 4, but some propitiatory plug that they don't sell a pigtail for. You have to go to another site to get the pigtail. For $30 + shipping you can get one. I just cut off their plug and put my own flat 4 on it, like it should have in the first place.
Otherwise I highly recommend this harness for your Jeep!

Great system. Much easier connectors than other systems I looked at. Videos gave me confidence to do it myself. Works like a charm.

This kit worked perfectly on my 2024 Wrangler. Easy to plug it all in. The only challenge is running all the wires through the chassis and back to front but that just takes patience and a mechanics rolling creeper.

  • Blue Ox Parts Needed to Flat Tow 2022 Jeep Gladiator Rubicon
    Hey Mark, so the correct Blue Ox base plate kit to use with the Blue Ox Ascent tow bar part # BX4375. is the part # BLU53FR. For lighting you can use # C96JR, and not have to worry about cutting into the taillight housing as this plugs inline with the taillight connectors. Then for the braking system the Air Force One part # SM99243 would be what you would want and you'd be set.

  • Is The Curt C96JR Tail Light Kit Compatible With A Brake Buddy Brake System?
    Hello John. The # C96JR tail light kit for the 2023 Jeep Gladiator will indeed work with a Brake Buddy brake System Such as part # HM39524. So, if you plan to use a portable brake system, that is definitely what I recommend, and you do not need to get something else.

  • No Splice Tow Bar Lighting Kit Recommendation for 2024 Jeep Wrangler
    Yes, we have the Curt tow bar wiring kit part # C96JR that is a confirmed fit for your 24 Wrangler. This installs by plugging inline with your taillight connectors which means it does not need any splicing.

  • Will The Curt Flat Tow Harness Also Work With Tekonsha Tow Harness on a 2023 Jeep Wrangler JL?
    Yes, the Curt Custom Tail Light Wiring Kit # C96JR will also connect with the T-One Vehicle Wiring Harness # 118786 on your 2023 Jeep Wrangler JL. These all use the same style factory connectors so they will plug in line of each other. If you have any additional lighting connected to the trailer connector on your Wrangler you will need to ensure you connect the Curt harness to the factory harness and then the Tekonsha trailer wiring into it then the tail lights so they get the power needed...

    Yes, it will! You'll want to cut off the 4-way connector of the Curt Custom Tail Light Wiring Kit for Towed Vehicles item # C96JR and install the 6-way connector that comes with the Curt Tow Bar 7-Way to 6-Way Coiled Adapter Cord w/ 6-Way Socket item # C59HR. With the 6-way installed you can use the included cord to connect it with the 7-Way on your RV. The center pin on the 6-way is wired for 12V power so this is where you'll want to connect your RVi Brake towed battery charger. I have...

  • Do the Diodes in the Curt Custom Tail Light Wiring Kit Keep the Braking System from Activating?
    No, they do not when you're not hooked up but that's not the issue. The Demco Stay-IN-Play Duo item # DM86VR needs the stop light signal from your motorhome in order to activate. If the system is activating when you're not connected then something likely is wired incorrectly. I would recheck your wiring to make sure everything is hooked up right. I have attached a diagram below to help you out. The diodes on the Curt Custom Tail Light Wiring Kit for Towed Vehicles item # C96JR prevents...

    Hey Dellos, the Blue Ox base plate and tow bars are in my opinion the easiest to use and are also very well made so I would recommend the Blue Ox part # BX1139 with the tow bar part # BX7420. Then for lighting the Curt kit part # C96JR is a very simple install so that would be a great choice as well. And finally, most states now require supplemental braking in the vehicle being flat towed. The easiest system to set up and use is the Blue Ox Patriot # BLU37TR, that applies the vehicle...

  • How To Power A Trailer Connector On A Towed Vehicle
    Towed vehicle wiring, like the Curt Custom Tail Light Wiring Kit for Towed Vehicles # C96JR, only sends power to the tail lights and wouldn't be sending anything to the trailer connector. You would need to wire a second connector to the back of the Jeep, like part # 47565, and splice it into the tail light wiring with some bonded wire # 16-4B-1 in order to get the signals from the lights for the bike rack.

  • Where to Find Price of Demco Flat Towing Products
    The 9519336 is the same as the # DM9519336 and the 9599006 is the same as the # SM99251. The price for these and all of our products can be found on the product page. We do not carry the 9523157. If you want custom wiring you can use the Curt # C96JR or if you want to stick with Demco you can use the universal # DM9523010-54.

  • Parts Needed For Installing Demco Stay-in-Play In A 2018 Jeep JL Wrangler Unlimited
    We can definitely help with that. The OEM brake switch in your 2018 Jeep JL Wrangler Unlimited is actually not usable for the purpose of installing the Demco Stay-in-Play Braking system # SM99251. You will not need any relays. Instead a Stop Light Switch # RM-751490 will be required for proper usage of this braking system. The Stop Light Switch will be what activates the indicator every time the brakes are applied. I have linked our install and review videos below if you want to take a look.
