Curt Custom Fit Vehicle Wiring - C55384

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into 7-way OEM tow package wiring harness - no cutting, splicing or tapping required.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Designed for use with a factory tow package that has a 7-way connector
    • Retains 7-way connector functionality
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points behind rear bumper
    • Plug in T-connector
  • Comes with dust cap for 4-way flat connector
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located behind the rear bumper. Simply plug the harness in-line with your existing 7-way wiring harness.


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.

I'm sure this product is great ,however I was looking to replace my factory installed ford explorer wire harness and the one that was sent does not have the proper gasket on the plug to fit into my vehicles original hardware. I've enclosed two photos which you can see show two different types of plugs. 544572


Comments

Unfortunately, this is an aftermarket plug, not an OEM so it wont necessarily be compatible with the OEM Ford mounting bracket. Your best bet would be to remove the existing bracket and use a # 18144
Mounting Bracket 4-Pole Flat
$8.91
mounting bracket. If there isnt a handy spot to mount the bracket, youd also need a # C57202

Took less then 5 min to install, solved the hassle of going to a brand name shop and paying 5 to 6 times to have them install. Plan on towing a utility trailer my wife and I do a lot of antique shopping. Will tell all my friends, great product 544551

Comments

The Curt # C55384 is meant for vehicles with the tow package which includes an existing 7-way trailer connector. You would unplug the factory wiring harness from the rear of the existing 7-way, and then plug the # C55384 inline with that connection. If your Explorer doesnt have the factory 7-way, you could use the # C56172

which would plug inline with the connector located behind the passenger side rear tire, next to the muffler.

Excellent product. Fits great! It took me longer to figure out how to unhook the wiring on the truck (without break it) than it did to install this 4 wire plug-in! I will shop with your company in the future. I've build many trailers and wired them to different vehicles over my life time. These plug-in wiring products are the way to go! 253635


Comments

Great product!Wiring harness works perfect. It was very easy to install. The worse part was getting my trucks harness to come apart. My truck is a 2014 Chevy Silverado so it had some dirt, etc making that connection a little tough to take apart without break it. But this wiring harness was great.Im getting old 76 and no longer build trailers from scratch. Ive laid on my back many times trying to locate the correct wires on a vehicle to install a connector and then solder the wires in place. These connectors would have made life a lot easier.

Am very pleased with this product. Having a new 2015 Silverado , I wanted to put a LED light bar under the tailgate. All the light bars that I found either plugged into the trailer light plug at the hitch or had to spliced into the truck wiring ,which I did not want to do, with this harness I was able to plug everything together no problem other than the long lead that had to be folded up and hid under the truck but it sure beat cutting and/or splicing wires. would recommend this harness, have recommended this harness, to anyone like who hates to cut or splice wires.works great, should last a long time,really glad I found it. 295183

I'll tell you and anyone else that this product is great and it allow me to hookup my under the tailgate lite with ease. One thing every one I talk to even the dealer were I got my truck. say's cut the wires and splits in. This harness is so easy to use and only takes mintues to do. But one word of caution when you disconnect the plug from the two way adapter. Make sure you remove the (WHITE TAB LOCK) and use a small screw driver down the lock channel to release the plug. Note for the supplier to need to provide the above info with your product. Thanks for a great harness. 149455

This is an excellent example of a well made product with excellent documentation and great packaging. It worked perfectly. And, it was here on the date promised. I used it to connect an LED light bar in a extremely clean fashion. the light bar came with a 4 connector trailer type connector. I didn't want to have the tail light bar permanently plugged into the bumper mounted plug from the outside. So, with this I was about to connect the lights with the connector hidden behind the bumper and still have full functionality of the bumper mounted connectors. 335480

talked to ashley a few days ago and she helped me with getting a trailer hitch and wiring harness for my 2015 jeep grand cherokee. awesome! quick shipping, received the hitch and harness in about 2 days. beautiful hitch, love it! for my jeep it was super quick to put on, unscrew four bolts, lift the hitch into place, replace the bolts and tighten. couldn't have been easier, perfect fit. wiring harness just had to take a cap off the vehicle connection, insert the new wiring and zip tie it down. no more than 20 minutes total to install the trailer hitch and wiring harness by myself (65 year old man!). would reorder any further items from etrailer without hesitation. super quick shipping and great friendly/helpful staff! thank-you etrailer! 301026

When i googled the question an answer from etrailer came up in the google search that suggested i buy this product. The video that was attached to the product made it a snap to install. If you haven't already i would also suggest including a 4 pin mount with this product as well as it will hang loose without it. 630946

I already installed it and was not about to take it back off for a picture but you can see on there picture of the product what I am talking about. its not the four way plug because it is plenty long enough. 625687

2018 Ram 1500

I installed my Curt T-Connector today to my 2018 RAM 1500 Sport 4x4 Crew Cab. The mileage on the truck is at 10679km's. Although warned that the spare tire might require removal (via web site info from fellow RAM owners) that was not the case as there was enough room to remove the OEM connector (which is the short end of the assembly) from the factory housing. The actual disconnect and re-connect took only a couple minutes. I spent a about 15 or 20min's trying different wiring run routings for the aux. four connector plug wiring run. Some tie-wraps where installed to snug things up out of the way and I was done. I also dosed the connections with a shot of Krown 77 lube/rust inhibitor. I'm in the "Great White North" so salt use on roads is a given during the winter months. A quick test run of the lights and I was done. The build quality of the T-Connector is very good..equal to OEM or better I'd say. 591009

  • Towing Capacity of a 2008 Ford Explorer Sport Trac
  • According to the owner's manual, the towing capacity of your 2008 Ford Explorer Sport Track is going to depend on your engine and hitch. With the standard factory Class II hitch you can tow 3,500 lbs with a 350 lb tongue weight regardless of engine. However, if you have a Class III or IV hitch, you can tow 5,000 lbs (4.0L engine) or 7,000 lbs (4.6L engine) with a tongue weight of 500 lbs. However, it is important to know what the maximum capacity of your hitch is; the lowest capacity of...

  • How to Add a Trailer Connector to a 2018 Jeep Grand Cherokee
  • I do not believe all 2018 Jeep Grand Cherokees came with a factory trailer connector. In order to add one you will want to first look under the vehicle's rear bumper near the spare tire for a USCAR car plug which I have attached a photo of for you. The plug may be taped to an existing wiring harness. If you have this plug then you can use part # C55384 to add a 4-way trailer connector or part # C55774 to add a 4 and 7-way trailer connector.

  • Wiring B&W Custom Headache Rack with LED Lights BWPUCP7500WA on 2017 Ford Superduty
  • The B&W Custom Headache Rack with LED Lights # BWPUCP7500WA is designed so that the two innermost lights will serve as taillights while the two on the outside work as brake/turn lights. These lights are fed by bonded 4-pole wiring like what is typically found in a 4-pole wiring harness. On the passenger side frame rail is a wiring connector you can use to access signals. Use of this connector will not cause the dash light messages.

  • 2015 Jeep Grand Cherokee Trailer Wiring Troubleshooting, 7-Way Not Active
  • Your 2015 Jeep Grand Cherokee may have the connector needed but it's not active. First, I would use a circuit tester such as # PTW2993 to test the 7-way connector to see if it's active. You may need to contact a Jeep dealer to have them activate the trailer wiring as it sounds like yours isn't. This is a fairly common issue that we have seen.

  • Can Installing Towing Package Components Increase Towing Capacity on a 2015 Chevrolet Tahoe LT?
  • Adding towing package components will help you maximize the towing capacity of your Tahoe LT, but it will not increase it. If you own the vehicle, it is up to you what modifications are made. The only way I can see it being prohibitive would be if it were to void a warranty of some type. I was able to find a towing capacity chart in your owner's manual for you to identify which vehicle you have. I have linked the chart to this page for you. If you decide you would like to continue...

  • Under the rear of your truck, near the back bumper, you should find the factory trailer wiring harness. It will probably be located on the driver's side frame rail, just behind the rear tire. The harness will terminate in a round plug that would plug directly into the trailer connector I'd recommend, which is the Hopkins # HM40975. This connector provides both a 7-way and a 4-pole. The round plug you find under the vehicle will have a protective cap on the end of it to keep out road...

Since your Jeep did not come with a factory 7-Way you may need to have the dealer reprogram the computer to activate the trailer wiring harness. The harness will plug into the connector though.

Since your truck has a factory 7-way and a small utility trailer would require a 4-way the wiring kit you'd want is the part # C55384 which installs in line with the 7-way and gives you a 4-way.

  • 4-Pole Wiring for 2018 Ford F-150
  • We have 4-pole wiring harnesses for the 2018 Ford F-150 such as Curt # C56110 which is a direct OEM replacement. This item and the similar Hopkins part # HM11140735 plugs in at the rear of the truck with a rectangular plug. Please refer to the linked photo. If instead your truck has a round U.S Car type connector you can use Curt # C55774 which includes both 4-pole and 7-way type connectors on one product.
