Features to know about

Installs Without Cutting or Splicing: Plug-In T-Connector

This Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector makes wiring simple. It plugs directly into your vehicle’s existing tail light connectors, so there’s no need to cut or splice wires. The plug-in design keeps the factory wiring intact while giving you a reliable trailer lighting connection.

Comparison image of Curt T-Connector Vehicle Wiring Harness models showing different connector designs and converter box configurations for trailer wiring applications.

Protects Vehicle Circuits: Powered Converter Box

The included powered converter keeps your vehicle’s electrical system safe by drawing power straight from the battery instead of the tail light circuits. That prevents overloading and ensures the trailer lights get consistent power for running, turn, and brake signals. It’s a smart setup that delivers clean, steady lighting every time you tow.

Clean Factory Look: Hidden and Secure Wiring Route

The harness features a hidden design that tucks neatly behind trim panels and routes through existing openings for a clean finish. Once installed, only the 4-flat connector is visible, ready for use when you hook up your trailer. Everything else stays protected inside the vehicle away from road debris or moisture.

Ready to Tow with Standard 4-Flat Connection

The 4-flat connector provides the essential lighting functions—running lights, turn signals, and brake lights—used on most small and midsize trailers. It’s a standard connection that’s easy to plug in and works with common trailer setups right out of the box.

Parts arrived quick, although the plugs were not an exact fit for my 1986 cj7 jeep, Sara R, was very helpful in getting me a diagram for the wiring so I could make them work. Sara also quickly responded to all my communications,and made the transaction a great experience.

One year later and everything works as it was when new.

No complaints with product. Easy Installation and solves my trailer light issue. I Love the plug cover. It keeps water and dirt away from the connector when not in use.

Installing wiring in ANYTHING gives me the chills so it was a very pleasant surprise to find out the kit installed exactly as promised...quick & EASY. I had this installed to a factory plug! No soldering or splucing! What a relief to find a kit that does exactly what you expect it to.
by:
The wiring kit was complete, with easy to follow instructions. It works as if were factory installed. If I need a related item in the future, I will definitely look to etrailer first.

Installed the wiring harness in minutes on my 1996 ZJ 4x4 5.2 engine. The real work was routing the wire (to the battery) in the undercarriage of the vehicle where it would be safe.

  • Installing Curt Trailer Wiring Harness 55260 on a 1995 Jeep Grand Cherokee
    When installing Curt trailer wiring harness # C55260 on a 1995 Jeep Grand Cherokee, both connectors will install on the passenger side of the vehicle behind the tail light and interior trim panels. Look for the matching connectors that look like the gray and black connectors on the harness. This harness is designed to fit on vehicles that have the factory tow package. If yours does not have the factory tow package the wiring may not be present or active for this wiring harness. If that...

  • Is The Curt 55027 Still Available And Is There An Alternate Wiring Harness That Will Work?
    The Curt 55027 has not been available for quite some time. The last one we sold was in 2015. I see that you were searching for parts for a 2012 Jeep Liberty. I can offer you the Curt wiring harness # C56334. This is extremely similar to the 55027 you mentioned. The main difference is that the new harness requires you to run a hot lead to the battery, while the 55027 did not. It looks like all of the wiring harnesses I have for the 2102 Liberty will require you to run a hot lead for 12v....

  • Trailer Wiring Recommendation for a 1996 Jeep Grand Cherokee Limited
    Your 1996 Jeep Grand Cherokee Limited most likely came with either no trailer connection at all or a 7-way round trailer connector. If you have a round connector at the rear of your vehicle near the hitch that looks like the part # 20135 then you have a 7-way. To see if you have the connection point to install the wiring harness designed for factory wired vehicles (part # C55260) you will need to look on the driver's side behind the spare. You will see an access panel there. Open it...

  • Recommended Trailer Hitch Wiring Harness For A 2019 Jeep Grand Cherokee
    Hey Mike, The Curt T-Connector Vehicle Wiring Harness # C55349 is designed to fit 1994 - 1998 Jeep Grand Cherokee's. Your 2019 Jeep Grand Cherokee would need the Curt T-Connector Vehicle Wiring Harness # C55664 if you have the factory tow package or the Curt T-Connector Vehicle Wiring Harness # C62VR if you do not.

  • What Is the Max Towing Capacity Of a 1998 Jeep Grand Cherokee
    According to my research, the most well equipped 1998 Jeep Grand Cherokee has a maximum towing capacity of 5,000 lbs. Unfortunately, we cannot recommend you tow more than this but since you are very close to the maximum towing capacity you would most likely be fine by just going over a few hundred pounds or so. That said, I cannot recommend this so you will just need to use your best discretion on what you think is right for your vehicle. For a trailer hitch, I recommend using the Draw-Tite...

  • Wiring Harness Recommendation for a 1998 Jeep Grand Cherokee without Factory Towing Package
    In regards to your 1998 Jeep Grand Cherokee both Curt T-Connector vehicle wiring # C55349 and T-One Wiring Harness # 118349 are very similar. They both receive great customer reviews. I would recommend Tow Ready Custom Fit Vehicle Wiring # 118349 as it is the more popular one as well. This wiring harness will connect inline to the plugs located behind the Jeeps tail lights. A separate power wire needs to be run to the positive post of the vehicles battery using the included in-line fuse...

  • What is the Converter Box Used for on a 1998 Jeep Grand Cherokee
    The converter box included with the vehicle wiring harnesses for this vehicle will avoid overloading the vehicle's electrical system. The converter box does this by drawing power directly from vehicle's battery as opposed to from each individual light circuit. For your 1998 Jeep Grand Cherokee, I recommend using the Curt T-Connector Vehicle Wiring Harness part # C55349 if you do not have the factory tow package or part # C55260 if you do have the factory tow package.

  • Curt T-Connector For A 2020 Jeep Grand Cherokee
    Hello Mike. The Curt T-Connector # C55349 that you ordered is for the 1994-1998 Jeep Grand Cherokee, which explains why it is not fitting your 2020 model. For the 2020 Jeep Grand Cherokee you will need the Curt # C62VR instead. I have linked our install video for you below. I will have customer service reach out to you to initiate a return.

  • Curt Trailer Wiring Harness that Fits 2017 Jeep Wrangler Unlimited
    Hey Felix, we have a trailer wiring harness from Curt that does fit your 2017 Jeep Wrangler Unlimited with the # C55124 but the one you referenced is designed for much older Jeep Grand Cherokees so it would not work for you. What kind of trailer do you have? The Curt I mentioned is compatible with LED trailer taillights.

  • Trailer Wiring Harness Recommendation for a 1994 Jeep Grand Cherokee
    It sounds like the converter box of the # C56496 has shorted out. If it's putting 12 volts on all three taillight circuits just because the battery wire is hooked up it has shorted out. For a replacement harness I would go with the part # C55349 as it will install inline with your taillights for an easier install.

  • Correct Hopkins 4-Way Trailer Wiring Kit for a 1994 Jeep Grand Cherokee
    The Hopkins Plug-In Simple Vehicle Wiring Harness # HM40555 that you purchase fits a 1992 - 1995 Ford Taurus Sedan. For your 1994 Jeep Grand Cherokee you need the Hopkins Plug-In Simple Vehicle Wiring Harness # HM42515 instead. We also have the Curt # C55349 and Tekonsha # 118349 wiring kits if you want some different options. All of these wiring kits will work well with your '94 Grand Cherokee.

  • Trailer Wiring Recommendation for a 1998 Jeep Grand Cherokee Laredo
    The final authority on whether or not a vehicle had a tow package would be a Jeep dealer for your 1998 Jeep Grand Cherokee. Or, you can see if your vehicle has the connector behind the rear scuff panel in the rear cargo area and then test it with a circuit tester like part # 3808 to determine if it is active. For more info on where this connector is check out the installation instructions I attached to the right for the # C55260. If it's there then the # C55260 would work as a wiring harness. Now...

  • Power Reaching Trailer Wiring Converter But No Power On 4-Way on a 1997 Jeep Grand Cherokee
    First, the Curt trailer wiring harness # C55260, is designed to fit if the 1997 Jeep Grand Cherokee came with the factory tow package. If yours does not have the factory tow package that could be the issue. There could also be some fuses or relays related to the factory tow package wiring, if you have it, that are missing or blown. On some vehicles, power can get through if there is a relay missing but the full power cannot go through the converter until said relay is replaced. Use the...
