T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - Jeep Grand Cherokee, 1997

Quickly and easily install a 4-way trailer connector on your Jeep Grand Cherokee with this custom wiring harness. T-One connector plugs directly into existing wiring. Powered ModuLite reduces strain on wiring system.

    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points in rear cargo area
    • Plug in T-connector
    • Run hot lead to car battery
  • Includes ModuLite to ensure that your Jeep Grand Cherokee's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading Jeep Grand Cherokee's electrical system
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector

    • Tail lights: 4 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One connector plugs into your Jeep Grand Cherokee's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.


Once installation is complete, the 4-way flat connector will be stowed in an out-of-the-way location within your cargo area.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your Jeep Grand Cherokee's three-wire system need to be combined so they are compatible with the wiring system of your trailer. This power module functions as a tail light converter to combine the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your Jeep Grand Cherokee operate.


With a ModuLite, your trailer's lights will be powered without overloading your Jeep Grand Cherokee's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

I ordered this converter for my 97 Jeep Grand Cherokee. After a 2-3 minute read of the instructions I proceeded to access the tailight plugs on my vehicle. You will need to remove the spare tire and open up both left and right side panels in the rear of the vehicle to gain access to the rear lights harness. After that it was simply unplug the existing connectors, plug in the adapter, route your wires under the tailgait cover panel, connect a power wire to a battery source and reassemble. Easy to do. Took me about 20 minutes and I was done. The Etrailer adapter kit was litterally plug and play. Works great. I am satisfied with my purchase and would recommend to anyone. 58212

To start off my harness was delivered 4 days after ordering.I dont know what there thinking over there @ e-trailer but it's suppose to take 7 days! lol. I am glad that it did come in so fast. The instillation was very simple (i did watch there video,very helpful.) took about 15 min. to hook the harness up ,the time consuming task is running your hot wire to the battery. And that just depends on how picky u are with your work. Then of all things it worked!! lol. It realy does work like it's supose too! e-trailer I give u an A+ Thank u for making my task easy. 5904

Very Good design and relatively easy to install. Works as described, was very impressed that my vehicle wiring harness was spared after the rental trailer I hooked up to deteroiating wiring shorted out. Since I prefer to run wiring along established safe routes within the vehicle (instead of as suggested in the installation instructions and video) an extra 2ft of primary lead wire and and extra foot in the right side signal harness would have been beneficial andf appreciated. 106172

Poor Instructions Product fits great. Instructions have you run the positive lead wire down passenger side, under vehicle, which is the side the exhaust system is on. Very difficult to keep away from heat no places to zip tie it to. I routed wire accross back of engine, zip tied it to existing wire harness, then pulled it through existing hole in fender. Under the vehicle on the driver side, you can zip tie it to the brake lines out of harms way. 1274

I am installing this harness this weekend so I cannot give a product review yet, but would like to praise Etrailer's service. Email confirmations were immediate and shipping was prompt! I recieved the harness within 3 days after placing my order! The price (with shipping) was much better than my local RV or auto parts store. This is my second purchase from Etrailer and I'm a satified customer! 18948

It works very well but I think the instructions need to be a lot more detailed for most people. It took some time to figure out a few things and the fuse that must be installed does not explain what to do very well at all, (Thats the yellow thing up there in the picture). Other then needing much better instructions it is a great product and I WOULD buy it again without any problems. 25517

Good. but tough to install Our 1998 Grand cherokee DID NOT HAVE the little access panel that is shown in the instructions and photos. That meant taking out several interior panels which was a huge problem since the fasteners usually break. The lengths of wire worked OK, but what a hassle getting access to the vehicle wiring! Our 1997 had the little access door the '98 didn't. 1816

Good but Worked well but the positive wire going to the battery needs to be several feet longer for the 98 Jeep Cherokee Kit. I had to run it on the inside of the vehicle to have enough wire and still barely had enough. Had to remove several interior trim panels in the process. 866

  • 4-Pole Wiring for my 1995 Jeep Grand Cherokee
  • Yes, you can use the Hopkins Vehicle Wiring Converter with 4-Pole End, item number HM48915, to wire your Jeep for a 4-way trailer connection. Keep in mind that this unit will need to be hard wired into the vehicles taillight circuits and that it only supplies 2.1 amps per function so the trailer can only have lights at the rear and no extra lighting. You will need to use a circuit tester, item number 3808 if you need one, to find the correct wiring to splice the connector to. An easier...

The wires needed to install a brake controller on your vehicle are not always available and sometimes if the wires are available they are not easy to find.

  • Towing Setup Recommendations for a 1997 Jeep Grand Cherokee Pulling a Boat and Trailer
  • The first thing you will need to do is check with Jeep to determine what the towing capacity is for certain. Next, you will want to get an accurate weight for the boat and trailer. Once you have those numbers we will be able to know what is safe for you to do with your trailer. In some states you are required to have trailer brakes on trailers that weigh over a certain amount. You will want to check with your local DOT to see what, if any, regulations are in place for trailer brakes....

The modulite converter on the wiring harness gets the power from the battery to illuminate the trailer lights. Your lamp outage sensor comes on when it senses a draw or lack of it on the lighting system, so the modulite bypasses this sensor and only uses the vehicles circuits as switches to tell the modulite when to turn on the...

  • Factory Wiring Harness that Does Not Work on a 1997 Jeep Grand Cherokee
  • If you have tested the trailer connector with a circuit tester like part # 40376, and determined that the harness not working has nothing to do with a blown fuse, then you will want to replace the converter unit. We have a T-1 Connector, part # 118349, that is specifically designed for your vehicle. The unit draws its 12V power directly from the vehicle battery, instead of drawing it through the vehicle lighting circuits. Installation is a snap, with no cutting or splicing required.

  • Do Converter Boxes on Trailer Wiring Harnesses Ever Go Bad
  • Converter boxes like what is on the Tow Ready Wiring Harness # 118349 can short out. Actually if there's a short on the trailer wiring they tend to short out pretty frequently. If you tested the input side of the box and the voltage is there when it is supposed to be, but on the output side of the box the voltage isn't there then it has shorted out and would need to be replaced. I attached an FAQ on troubleshooting 4-ways for you to check out also.

How you'd proceed next will depend on the connector use on the trailer you'll want to pull. I'd recommend using a 7-way because it's the most common. You can always use an adapter like part # HM47570 to convert it to anything else you'd need. To actuate the electric brakes on the trailer, you'd need a brake controller.

  • Can I wire the Trailer Connector Directly Into Taillight Circuits on my 1995 Jeep Grand Cherokee?
  • If you were to wire your connector directly into the taillight circuits, your trailer lights would not work properly. Your Grand Cherokee uses separate circuits to carry the turn signals and the brake lights. However, your trailer combines both these signals onto one circuit. The converter, part number 118349 is needed to convert the separate signals from the vehicle into the combined signals that the trailer can use. The modulite with the separate battery feed is needed to protect the...

  • How to Use 4-Pole Trailer Connector # 118349 Once Installed on 1998 Jeep Grand Cherokee
  • Once installed, the 4-pole trailer connector would be stored in the cargo are of your Grand Cherokee. When needed, open the hatch and pull out enough of the connector and wiring to reach the connector on the trailer. Then, you can close the hatch on the wire. The rubber weather stripping around the hatch is plenty thick enough to cushion the wire and prevent it from being damaged, as long as you keep the wire well away from the latch.
