Features to know about

Blazing Fast Installation: Plug-and-Play Design

If you're not a fan of complicated installs, this custom wiring harness makes it so easy, even a novice can set it up in just 10 to 15 minutes. It’s a straightforward plug-and-play system that requires no cutting, splicing, or tapping into your vehicle's wires. Just plug in the T-One connector into your vehicle’s existing wiring harness and you're ready to go. It turns what could be a tedious task into the easiest part of prepping your Jeep Cherokee for towing.

Protects Your Connection: Tail Light Converter

Trailer lighting systems can differ from vehicle systems, but the integrated tail light converter in this harness makes sure your brake and turn signals are compatible. This converter handles the transition so you won't experience mismatch issues with your lights. Worried about interference or signal glitches? Not an issue here—the converter ensures reliable, hassle-free operation every time you connect a trailer.

Reliable Performance in Any Condition: Dust Cap and Corrosion Prevention

The dust cap included with the 4-way flat connector offers additional protection against dirt and moisture—two of your trailer wiring’s worst enemies. Pair that with a quick dab of grease on the connections, as recommended, and your setup is primed for longevity. Enjoy peace of mind knowing that your setup is protected from the elements, minimizing the risk of corrosion over time.

Clever Storage Solution: Concealed Installation

Instead of dangling wires or hard-to-reach connections, this harness offers a concealed installation. Once the harness is hooked up, you can safely stow the 4-way flat connector in your rear cargo area, keeping it tucked away when not in use. This neat approach not only keeps things tidy but also eliminates tripping hazards and unnecessary wear and tear on your wiring.

Versatile Compatibility: Fits a Wide Range of Models

Don’t worry if your Jeep Cherokee model is from 1997 to 2001—this harness has you covered. It fits most models within this range, no matter if it's a sport or a classic. Plus, its design takes the guesswork out of fitment, ensuring it pairs perfectly with your vehicle for an uncomplicated install and highly reliable operation out on the road.

  • Recommended Brake Controller and Parts Needed to Add 7-Way to 2000 Jeep Cherokee
    You can install a 7-way in your 2000 Jeep Cherokee but there is no plug-in harness for this vehicle, you are going to need to add a number of parts. First you need to add a 4-way, the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118354 and I have linked a video so you can see how this installs on a '00 Jeep Cherokee. From there you are going to need the Universal Installation Kit for Trailer Brake Controller # ETBC7, which will give you a 7- and 4-way adapter (this...

  • Parts Needed to Install a 7-Way on a 2000 Jeep Cherokee
    First you will need to install the Tow Ready Wiring harness part # 118354 that you referenced. Now if all you need is taillight functions then to convert to a 7-way you would only need a Adapter 4 Pole to 7 Pole # 37185. If the 98 Dutchmen camper has trailer brakes you will need a brake controller and instead of the # 37185 you would need a Universal Brake Controller Installation Kit part # ETBC7. This kit comes with everything needed to install a brake controller and install the included...

  • Recommended Parts to Tow a Small Trailer with a 2000 Jeep Cherokee
    I'd be happy to make some recommendations for you! To tow a small trailer with your 2000 Jeep Cherokee you need a hitch, wiring, and a ball mount. Here are my recommendations: etrailer Trailer Hitch Receiver - # e97AR T-One Vehicle Wiring Harness - # 118354 B&W Tow & Stow 3-Ball Mount - # BWTS10048B I really like the etrailer hitch because it has a matte black powder coat that is more durable than the standard glossy powder coat, and it looks the part as well. The T-One wiring is the...

  • Trailer Lights Not Working on 2001 Jeep Cherokee With Tow Ready T-One Wiring Harness # 118354
    On the Tow Ready T-One Wiring Harness, part # 118354, if you find some, but not all, lighting functions work properly you may have a ground problem. In this situation a weak ground is just strong enough to provide some lighting functions but not all. When the taillights and brake lights are used at the same time, it creates the maximum amp load of the lights on the trailer. If a ground problem exists, it will show at this point. The places to check grounds are the connector on the vehicle....

  • What is Towing Capacity of 1999 Jeep Cherokee Sport
    I looked up the towing capacity of your 1999 Jeep Cherokee Sport and found that it can tow up to a 5,000 lb trailer so it would easily handle a boat that weighs 947 lbs. The Draw Tite hitch part # 75054 that you referenced is a confirmed fit for your Cherokee as well and would wok great as it also have more capacity than you'd need. You'll need trailer wiring to so that you can control the lights of the trailer. For that you'd want the part # 118354 which installs easily and is very reliable. Since...

  • Wiring Harness for 2001 Jeep Cherokee
    The Upgraded Circuit Protected Tail Light Converter Hardwire Kit w/ 4-Pole Connector and Circuit Tester # 119178KIT is a universal kit that can be mounted on the frame under your 2001 Jeep Cherokee, but it is not the best location for it and it could possibly be damaged. I strongly recommend forgoing the use of this universal kit that can be a difficult installation and instead using the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118354 which is designed to fit your...

  • Correct 4-Way Wiring Harness for 1997 Jeep Grand Cherokee
    The reason the # 118354 did not fit is because it is designed for the 1997-2001 Jeep Cherokee. The correct wiring harness for your 1997 Jeep Grand Cherokee will depend on whether or not you have the factory tow package. If you have the factory tow package, I recommend the Curt # C55260. If you do not have the factory tow package, then you want the # 118349 instead. These are the most reliable options for your Grand Cherokee with/without the tow package. I have attached some review videos...

  • Recommended Trailer Hitch for 1997 Jeep Cherokee
    The Draw-Tite Class I receiver you mentioned, part # 24827 is a vehicle-specific item that will fit a 2005-2010 Scion tC only. To see the various hitches available for a 1997 Jeep Cherokee, click the provided link. I would recommend the Curt Class III receiver, part # 13160. A Class III receiver will allow you to maximize the towing capacity of your Cherokee. The more common 2 inch receiver size will also allow you a better selection of hitch accessories like bike racks or cargo carriers,...

  • Does Curt Hitch Fit All Models Of 2000 Jeep Cherokee XJ and Trailer Wiring Recommendation
    The Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" part # 13084 is a fit for all models of the 2000 Jeep Cherokee however XJ is not a model. XJ is what the second generation (1983-2001) of Jeep Cherokees are called so the hitch will fit your 2000 Jeep Cherokee however it will require drilling through the frame mounted, closed sided steel skid shield if the Jeep has one which is why I recommend the Curt Trailer Hitch Receiver part # 13160 because it does not require drilling at...

  • Availability of Plug and Play 4-Way Wiring Harness for 1991 Jeep Cherokee Laredo
    The only option available for your 1991 Jeep Cherokee Laredo is a universal kit. The # 118354 wiring harness you looked at only works with the next Cherokee model starting in 1997. I recommend the Upgraded Circuit Protected Tail Light Converter Hardwire Kit # 119178KIT. We have found Tekonsha to be the most reliable when it comes to wiring. This kit includes a circuit tester and 5 quick splices to help out with the installation.

  • Trailer Wiring Harness for a 1998 Jeep Cherokee
    If your 1998 Jeep does not already have a trailer connector then you will need to install a wiring harness in order to power the lights on the trailer. You can use harness # 118354. I have linked a video showing how it installs on a 1997 Cherokee. The process will be the same on your 1998. Once the harness is installed you will have a 4-Way flat trailer connector at the back of the Jeep.

  • Flat Tow Wiring Options For 1997 Jeep Grand Cherokee
    Hello Robert, thanks for reaching out. We do offer flat tow wiring options for the 1997 Jeep Grand Cherokee. There are no plug and play pigtail options though. What I recommend is the Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles # RM-15267. This does require splicing in diodes behind the tail lights and running wires up to a 6-pin plug at the front of the Jeep. This is my preferred method because it is safe to add to virtually any vehicle, and once you are done all you have...

  • Brake Controller Recommendation for 2001 Jeep Cherokee for Camper with 7-Way
    You will need to start with a 4-way (if you do not have one). For that you would want the # 118354. I attached an install video for this for you to check out as well. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7.

For trailer wiring you would want the part # 13084. I attached an install video for this product as well.

    Though I'm not 100 percent sure what you are referring to in terms of "clearing" the skid shield, there are different installation instructions (which are linked) for both hitches in regards to that shield on your 2001 Jeep Cherokee which may be what you are looking for. Curt hitch # 13160 will give you 20 inches of clearance from the ground, and according to the install manual you are going to loosen the skid shield's bolts and place the hitch flange between the Jeep's frame and skid...

This particular custom harness is designed for the 1997-2001 Jeep Cherokee, so your 1994 model will not have the needed factory ports for this to plug into.

Instead, you will want to use the etrailer Trailer Hitch Receiver # e97AR which has a 2" hitch receiver and matte black finish. For a complete towing kit, you can add the T-One Vehicle Wiring Harness # 118354 and the etrailer Ball Mount Kit # 989900.

I recommend that you purchase a Curt # 13084 Class-III hitch which has a 2” receiver and more towing capacity than your Jeep is rated for. In the future you may wish to tow heavier trailers or loads that will require the Class-III hitch. You might also consider accessories...

    The Curt Class III Round Tube Receiver Hitch # 13160 is compatible with your 2001 Jeep Cherokee and requires no drilling or welding for installation. It is rated for 5000 lbs., however you will still be limited to the towing capacity of your Cherokee which, from my research, is only 2000 lbs.
