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.

Video Transcript for Curt T-Connector Vehicle Wiring Harness Review

Speaker 1: Today we're gonna be taking a look at and installing the Curt T-connector vehicle wiring harness for factory tow packages that is a four-pole flat trailer connector, part number C55384. This harness provides you with a four-pole flat connector for your trailer and installs without any splicing or cutting required, and just plugs inline with your vehicle's factory seven-way connector. Connector will plug in on this end, and this will plug in to your seven-way connector. Unlike other options, this will let you have your four-pole connector while still maintaining operation of your seven-pole connector. So no matter which trailer you decide to hook to, you can just set it up and you're ready to go. It comes with a protective wire loom already installed, so that way when you're zip tying it up to your frame wheel or anything, you don't have to worry about it rubbing through.

And it measures about 45 inches in length, so you can take that into consideration when routing your wiring.The four-pole connector end has a dust cap to keep out any dirt or debris, and it can also be used to secure it to your safety chains on your hitch. The four-pole connector is gonna give you your left turn signal, right turn signal, tail lamps and brake lamps so you'll have all the necessary DOT required lighting on your trailer. Some of our customers have been using this to hook up additional accessories. One of our customers, Andrew K, had to say, "Product works great. Only took ten minutes to install and wasn't difficult at all.

Bought this to power an LED light bar under my tailgate while still using the factory plug for towing and it works perfectly."Now we'll show you how to get it installed. This is gonna work with any vehicle that has a factory seven-pole connector. We're here at the rear bumper at our seven-pole connector, where you'll find this connector located behind your rear bumper. We'll disconnect it from our seven-pole here by pressing in on the release tab and pulling outward. You can see that release tab here.

It just pushes in. We're now ready to connect it to our harness.Before we plug it in, it is a good idea to use some dielectric grease to fill out the inside around all your terminals. This will help keep out any moisture or corrosion. You can pick up some dielectric grease here at etrailer.com with part number 11755. Now we're not gonna be installing any dielectric grease today for demonstration purposes.

So now we'll take our male connector on our new harness, plug it in to the female end on the vehicle, and then take the female end of our new harness and plug it in to our seven pole connector. Now we can just route our four pole wiring power where we desire, zip tie it up to make it nice and clean, and now we're ready to test it out. The best way to do this is to hook it up to your trailer. Or you can use a tester such as the one like we have here. You can pick up one of these testers at etrailer.com.We have our left turn, right turn, tail lamp, and brake lamp. And with everything working properly, we're ready to hook up our trailer and hit the road. And that completes our look at the Curt T-connector wiring harness for factory tow packages that has a four-pole flat trailer connector.

Wiring kit was perfect for my Jeep. I had to have the vehicle flashed for the Jeep to recognize that I had a trailer hitch. Just another way for the dealer to make money. Vehicle had factory plug for a trailer. 636108

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

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

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.

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
$9.10
mounting bracket. If there isnt a handy spot to mount the bracket, youd also need a # C57202

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 used this T plug to add a tail light/brake light/turn signal bar on my 2019 Silverado crew cab it worked as advertised I would of gave it a 10 if the 7 way adapter wasn't so short if they had made it at least an inch or two longer it would have made install much easier. 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

Awesome!! I bought an OPT7 triple LED light bar for my Chevy Colorado and I didn’t want to splice wires or lose a whole lot of time trying to figure out how to wire it up so I googled and I came across a gentleman who used this product and Im very thankful for this connection and my light bar works smoothly and I have full use of the reverse camera AND I don’t have any wire mess outside or underneath my truck! Easy to install, my first time doing this and it literally took me about 2 minutes, if that! Definitely would recommend this product to anyone with a truck!! Thank you guys!! 673015

The # C55384 is only compatible with vehicles that were equipped with the factory tow package. If the vehicle wasnt so equipped, the round connector will not be present at the rear of the vehicle. In that case, you would need to use # 118390

  • Trailer Hitch and Wiring for 2015 Jeep Grand Cherokee Altitude to Tow Boat Trailer
  • For your 2015 Jeep Grand Cherokee the trailer hitch I recommend is the Draw-Tite # 75699, which is a 2" receiver with a maximum tongue weight of 750 lbs and a maximum towing capacity of 5,000 lbs. This hitch has gotten universal praise from our customers, with over 450 reviews giving it a nearly unanimous 5 stars.

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.

I've linked a video of the install on a 2010 Sierra which will be the same for you. If your truck is not a 1500 then let me know so I can make the correct recommendation. Also, if you need trailer wiring I recommend part # C55384 for a 4-way connetor or part # 30955 for a 7-way. Whichever connects to your...

  • Trailer Wiring Harness that Does Not Require Splicing for a 2016 Chevy Colorado
  • I have a solution that will not require cutting and splicing wires but there isn't a plug and play harness available for the 2016 Chevy Colorado. What I recommend is the ZCI wiring harness # 119250KIT. This harness has connectors that clamp around the vehicle tail light wiring that sense the current running through the wires. No need to splice!

  • Class V Trailer Hitch for 2005 Chevrolet Silverado 2500 with 6-1/2-Foot Box
  • Yes, the Curt Class V hitch # C15302 is a confirmed fit on your 2005 Chevrolet Silverado 2500 with the 6-1/2-foot box as long as it has the factory bumper. This hitch bolts on using the included hardware kit and no drilling is needed to mount it. Wiring kits for the truck are linked for you in case you also need a 4-pole like # C55384 or a 7-way like # C56070, both of which connect using a round U.S. Car type connector like what's shown in the included photo.

  • Trailer Wiring Harness for a 2001 Toyota Sienna
  • There are several different wiring harness that will fit your 2001 Toyota Sienna and I have included a link to them for you. However, the harness that you referenced, # C55384, will not fit your Sienna. For a harness that plugs in line with the vehicle tail light wiring you can use # C55418. I have included a link to the installation instructions for you to view.

  • Recommended 7-Way Trailer Connector for 2014 Ford F150 STX
  • 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...

  • Best In-Bed 5th Wheel/Gooseneck Trailer Wiring for a 2015 Chevy Silverado 3500HD

It will plug in line right behind the factory 7-Way. I have included a link to a video showing installation on a 2014 model for you.

  • Trailer Hitch Recommendation for 2019 Ram 1500 Classic for Small Utility Trailer Towing
  • For a light duty towing application for your 2019 Ram 1500 Classic without the towing package the hitch you'd want is the etrailer.com part # E98852 because it's an easy install, has more capacity than you'd need at 6,000 lbs trailer weight, and has a great price. 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. Since you wanted to do some...

  • Installation of Trailer Wire Harness Extension to Fit Aftermarket Bumper and Factory Connectors
  • It sounds like you already have the factory 7-way on your truck and just need a short extension. There is not a basic extension available without the 7-way, so I recommend the Reese Multi-Plug Wiring Harness for Factory Tow Package - 7-Way and 4-Way Flat Trailer Connectors # 74682. This should give you the short extension needed for your aftermarket bumper. If you have a longer connection need, then I recommend the Pollak 5th wheel and goosenesk trailer connection # PK11932 which will...

  • Adding 4-Way Connector To 2014 Jeep Grand Cherokee With Oem 7-Way Wiring
  • We have a few options that will work for your 2014 Jeep Grand Cherokee. If you want to retain the 7-way connector at the back of your Jeep and add the 4-way connector The Hopkins 7- and 4-Pole Trailer Connector, part # HM40975 will work well for you. My on ly concern is if you have the length from the existing 7-way to plug into the back of this connector. If so, then you are good to go. Another connector you may want to consider is the Curt T-Connector Vehicle Wiring Harness, part...

  • Trailer Wiring Harness for 2015 GMC Canyon
  • If your 2015 GMC Canyon has the factory-installed tow package the truck will have an actual 7-way trailer socket at the rear bumper rather than the punch-out plate. You can still check under the back bumper for any wiring/connectors. If you find a round U.S. Car connector (see photo) then you can install a 7-way/4-pole socket # HM40975. The vehicle connector will plug right in to the back of the Hopkins. The 4-pole harness you referenced, part # C55384 from Curt, also uses these same...

  • Does Brake Controller on 2000 Ford Ranger Need to be Hardwired?
  • There is not a plug and play option for a brake controller on a 2000 Ford Ranger; installing a brake controller such as the Primus IQ # TK90160 will require you to hardwire the unit. You can take a look at how to do this by checking out the help article I've linked detailing how to install a brake controller. You will also need a 4-flat, part # 118344 if you do NOT have the factory tow package or # C55384 if you do have the factory tow package. Additionally, you need the Universal Installation...

  • Can Second 4-Way be Added to 2016 Ram 1500 With 7-Way and 4-Way
  • Since your 2016 Ram 1500 already has a 7-way and 4-way you would not be able to add another connector with the Curt T-Connector Vehicle Wiring Harness # C55384. To add a LED light bar such as the Rampage SuperBrite LED Tailgate Light Bar # RA960134 or Bully Fire Strip LED Light # BLS-1101 on your '16 Ram 1500 you would need to use your existing 4-way.

  • 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.
