Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the rear bumper, on the driver's and passenger's sides. You will have to remove the protective plastic covers on either side of the bumper to access the connection points.


Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


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.

Video Transcript for Trailer Wiring Harness Installation - 2004 Jeep Wrangler

Today on our 2004 Jeep Wrangler, we'll be installing the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part number C55363. Now, to begin our install, we'll first go underneath the driver side taillight assembly and locate the plastic cover that covers up the rear portion of the body. Once we locate the plastic flap, we'll need to peel it back, but before we do that, there's a push-pin fastener that need to pulled. You can use a flat-blade screw driver or plastic trim panel tool just to pry that plastic fastener out, and we'll pull a bit down on the flap. Once we have it down, we can expose the manufacturer's electrical connector here and note that it sometimes can be wrapped in foam to help protect it from the outside elements. Since this one's already been removed, we're going to press on the connector lock and separate the two connectors. There it goes.

Next, we'll bring in a new Curt wiring harness using the yellow and brown wire connector end here on the driver side, we'll connect in-line with the manufacturer wiring. Matching the manufacturer's connectors and plugging directly into them, making sure we've got a good secured connection. Next, I'm going to take the 4-pole connector, bring it over the frame towards the center of the vehicle. I'll follow that with a green wire connector that's going to get run over to the passenger side and we'll repeat the same process. Now with our wire temporarily run, we're going to move over to the passenger side where we're going to go ahead and pull down the underbody panel so that we can gain access the main sets of wiring on the passenger side. Again, we'll need to remove the push-pin fastener and pull the panel down.

We'll locate the connector, remove the protective cover, so that we can gain access to the connector lock. Press on the lock and separate the two. We'll then take the white and green wire connector, feed it over the frame, and behind the panel where we can make our connection. Keep in mind when routing your wires, stay away from any moving components such as standard suspension or excessive heat such as exhaust. Now that we made our connection, we're going to take the white wire with the pre-attached ring terminal and secure it here to the body of the vehicle. Note when locating our mounting location, I recommend to find an area where the sheet metal doubles up just like this for a good secure ground.

Using a self-tapping screw provided with our install kit, we're going to run the self-tapper directly into the sheet metal to secure it. I'm going to go ahead and put my wiring back up behind the taillights assembly and secure the wiring as necessary with the zip ties provided with the install kit. Now, when I secure my wiring, I'm going to start here in the center, figure out the length of wire I need to run out through my hitch accessory, and then secure it to the manufacturer's wiring behind the gas tank and up next to the frame of the vehicle. Now that we've finished securing the wiring, we'll go ahead and cut off the excess from the zip ties to clean up our install look. Now we've got our install cleaned up, we're ready to reinstall the underbody panel with our push-pin fastener back in place to hold it. That's it for the driver side.

We'll move over to the passenger side and repeat the same process. Now, with everything put back, that'll complete our install. Now to test our new 4-flat trailer connector, we'll start with the white wire terminal or the bare pin, putting our ground clamp on it. Then we'll test the next terminal over which is the brown wire terminal for the running light circuit. The yellow wire terminal for the driver side turn signal and brake. Then the passenger side turn signal would be the green wire and brake. There, in just a few simple steps, we've gone ahead and installed our new T-connector wiring harness and tested it. We're now ready to hit the road. That does it for the install of the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part number C55363 on our 2004 Jeep Wrangler. .

Bought the Curt hitch and wiring kit for 2013 Highlander and was entirely pleased with product, installation instructions, and performance for a couple years. Recently traded the 2013 for a 2019 Highlander and have bought the same hitch and wiring kit for it. 100% positive recommendation for etrailer, their products and customer service. 720919

High quality and simple install with video. There will only be about 3 ft of pigtail going toward the front bumper (if you are wiring for flat tow) so get the tow bar wire kit too. 649351

very easy kit to install, it took me about 20 mins. to put on. the only part that someone may not like is creating a ground, however, there are many places to place the ground wire without drilling, should you choose. shipping was fast, arriving much sooner than I thought, and communication from the company was prompt and helpful. I would definitely order from them again, and recomend this kit to other out on the trails. it saves you a good bit of money to do this yourself, as opposed to taking your vehicle into a shop. 546072

Ask the Experts about this Curt Custom Fit Vehicle Wiring

  • Curt 4-Pole Wiring Harness C55363 Installation in 1999 Jeep Wrangler
    Curt 4-pole wiring harness # C55363 is a correct fit for your 1999 Jeep Wrangler. If you find that the turn signals are reversed for left and right this just means you need to switch the plug-in connectors to the opposite sides of the vehicle. The connectors with the yellow wire should plug in at the left/driver side tail light; the connector with the green wire should connect on the right/passenger side light. For reference I linked an installation video showing a 2004 Wrangler.

  • Troubleshooting Short on 2017 Hyundai Santa Fe with Curt Trailer Wiring Installed
    The Curt harness part # C55363 is probably not the real reason your lights shorted out, but it probably helped it happen. What would have had to happen was that your trailer's wiring put a short on the circuits of the Curt harness which then transferred to the vehicle and caused the light to stop working. The harness is just wires without any type of circuit board so it should still be fine unless there's melted or exposed wire on it. Which that would indicate a massive short on your...

  • USA Made Trailer Wiring Harness Recommendation for 2003 Jeep Wrangler
    I wish I could say yes to that but no they are not. For a made in the USA trailer wiring harness confirmed as a fit for your 2003 Jeep Wrangler we have the Curt kit part # C55363 which would work great. I attached an install video as well.

  • Wiring Fit and Compatibility on a 2006 Jeep Wrangler-X
    If you don't have a factory 7-way already on your vehicle the Hopkins wiring harness # 32625, the Tow Ready # 118409, or the Curt # C55363 will fit for your 2006 Jeep Wrangler-X. I recommend the Tow Ready # 118409, because it is the most popular among our customers. I have linked all the wiring harnesses that fit a 2006 Jeep Wranger-X without the factory tow package for your vehicle for your convenience.

  • Hitch & Ball Mount for 2002 Jeep Wrangler to Clear Spare Tire
    You can avoid clearance issues between your 2002 Jeep Wrangler's rear-mounted spare tire and your towing ball mount by using a ball mount long enough that will extend past the rear edge of the tire. The 2-inch hitch I suggest for your 2002 Jeep Wrangler Unlimited is Curt # 13408. This is a no-drill bolt-on installation. When we installed a Class III hitch on your vehicle we found that the distance from the hitch pin hole to the rear of the spare tire was 6-1/4-inches. Once it is installed...
