Quickly and easily install a 4-way trailer connector on your Chevrolet Silverado New Body 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 Chevrolet Silverado New Body 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

Installation

This custom-fit T-connector plugs into your Chevrolet Silverado New Body'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 Chevrolet Silverado New Body, 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.

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

2015 Chevrolet Silverado 1500


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

I purchased the wire harness to go with my class 3 hitch for my 2017 Nissan Titan King Cab. The harness was intended to be inserted in the current harness with the factory tow package which I did not have, I just removed the cap in the end of the current harness and inserted into the open end of the new harness. The harness does not come with a hanger for the 4 pin plug so I just tie wrapped it out of the way where I could get to it easily. Very easy to install once you figure out how to release the cap by depressing the tab. Quick and simple for the average guy. 415333

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

This is the second Curt T connector I have purchased from eTrailer among several other items over the last few years. Each product has been exactly as described and of excellent quality. The first Curt T connector was installed on a truck I sold in order to put myself into a new Tundra. This one will be used to access power for bed lights and an aux 12v power connector under a hard tonneau cover. It can also provide power for a tailgate led light bar. Cannot supply a photo with this review since it will be a few days before installation. 349289

Excellent: Purchased a Curt trailer hitch C13065 and Curt T-connector - 4 Pole C55384. Crawled under the back of the Jeep with a friend to help, removed 4 factory installed bolts, lifted the hitch and re-installed bolts in 20 min. Easy. Because I watched the youtube video, I installed the T-connector in 5 min. one person job. Towed a 6x12 trailer full of furniture across multiple states with no problems. Note, it took the Jeep dealership 5 hrs. to figure out how to provide power to the factory installed tow wiring. 493503

This is the only way to hook up under tailgate light. Just pug in and its done. But the etrailer.com folks need to provide instructions on removal of vehicle plug. I call etrailer.com and they showed me to instructional video and after review the white pug lock I removed needs to stay in and only raised just a little and sqwees white lock the the main pug is released. Only the video show this but did not enphize it. Other wise its a good product and my second one. So stop fooling around and buy it! 280527

I ordered a trailer hitch, wiring harness and MaxxTow ball mount for my 2015 Ford Explorer. After viewing the rectangular wiring harness plug on my vehicle, I immediately called customer service who substituted the flat wiring harness plug for the round one ordered. The customer service associate substituted the correct wiring harness despite costing about $4.00 more. Excellent customer service and I received all parts ordered one day earlier than promised. 407555

This item came as promised in only a few days, it appears to be of good quality, how ever will not fit my 2011 ford ranger so I'm gonna see if I can return it. If my trk was set up to accept this harness it looks like it would have been a 10 min job to install. The only reason I didn't give 5 stars is because I never took it out of the package but so far ordering and receiving this harness was very prompt and price I thought very reasonable. 519938

I used this product to give me an extra dedicated 4 wire trailer connector to use for my under the tailgate lighting, leaving my original 4 wire connector free to use for my trailer. Worked great. Only took a few minutes to install. If I were installing a tailgate light bar on any truck again, I would definitely use one of these connectors. I highly recommend this product to anyone needing a 4 wire trailer connector. 363156

One year later I still think I made the best decision, using this product. Everything still working great and I can connect my trailer anytime I want without disconnecting me under the tailgate lights. Great product !!!

I have ordered from etrailer.com for years and never left a review...it's time. I am at the point where I don't compare other shops online or especially locally. Their videos for installation let me know what I'm into before I take the job on. This install and wiring was the easiest ever. Factory look with a better than factory rating is a win win. Love buying from these guys! Makes my life easier. 269214

I purchased this product to use in installing tailgate led strip. Using this product has made installation smooth and simple, and still leaves my factory 7 pin available for hooking up a trailer without having to disconnect my lights or having to have an unsightly adapter plugged into my 7 way. Will purchase again for future installs on other vehicles. I highly recommend this product, and seller. 500999

Excellent product quality, easy install and will definitely use again on next vehicle. I purchased this item in order to give me a way to wire up a extra set of off road lights in the back without having to splice into factory wiring and give me the added benefit of not running a toggle switch to the new lights. Once i'm ready again on my new truck will be buying another harness. 526629

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.

I just installed this on my 2018 Jeep Grand Cherokee Laredo. Super fast and super easy to plug in/attach. The instruction video was spot on.

  • 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 # 3808 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.

  • Trailer Hitch and Wiring for a 2017 Dodge Durango
  • For your 2017 Dodge Durango you can use Curt trailer hitch # C13182. This is a Class III hitch with a 2 inch receiver that fits all models of the 2017 Durango (R/T models with dual exhuast will require trimming of the heat shield and fascia, and full-size spare will not be able to be stored under the vehicle). I have included a link to a video showing an example installation for you. I also recommend etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise...

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.

  • 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.

  • 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 accompanying photo shows how the hitch looks when installed on a Grand Cherokee. For a wiring harness, if you do not have a factory tow package you need the T-One Vehicle...

  • 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...

  • 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...

  • Wiring Dome Light and Third Brake Light on a Camper Shell on a 2009 GMC Sierra SLE
  • The Curt T-connector # C55384 has a 4-Way flat connector on it. The functions that it carriers are running lights, left turn/brake lights, right turn/brake lights, and ground. If the dome light runs off of the running light circuit and the wiring on the camper shell has a converter that separates out the combined turn signal and brake lights to only include the brake light then this harness will work. However it is probably not likely that the camper shell is wired this way. If that...

  • Recommended Wiring Harness for a 2014 Jeep Grand Cherokee Without a Tow Package
  • Your 2014 Jeep Grand Cherokee may have the connector needed but it's not active. First, I would use a circuit tester such as # 3808 to test the connector to see if it's active. 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. There are 3 trailer wiring kits we currently offer that works with your 2014 Jeep Grand Cherokee as long as the connector...

  • Installing 7-Way/4-Pole Trailer Wiring Harness on 2013 Chevy Traverse LT
  • I do have a solution that would allow you to install the # HM40975 on your 2012 Traverse. I assume the socket you've found on the passenger side frame rail, to the right of the muffler as shown in Diagram 'C' that I provided. You would first install the Tow Ready # 118271 that you mentioned, because you need the fuses and relays to activate the tow package as well as the pigtail. On the rear of the 7-way where the pigtail meets the trailer connector, you'd slide up the gray locking clip...

  • Trailer Wiring Harness for 2016 Silverado 1500 Without Tow Package
  • For a 2016 Silverado 1500 without the factory trailer wiring option you can use one of the trailer wiring harness kits shown on the linked page. Your truck will have a round U.S. Car type connector under the rear bumper. To this you can connect a 4-pole type harness like # C55384 or a 7-way like # 41157. A 4pole connector carries only stop, turn and taillight signals. A 7-way carries these same signals plus three additional circuits, typically for trailer brakes, 12V auxiliary trailer...

  • Recommended Hidden Wiring for Tailgate Light Bar on 2018 Ford F-250 Super Duty
  • The Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector # C55384 will work perfectly with a light bar but it will give the trailer connected on the dash and the other trailer associated changes that your truck recognizes. The only way around that is to splice the tailgate light bar pigtail into the factory wiring so the sensors don't get triggered for the trailer compatible electronics. For your tailgate light bar on your 2018 Ford F-250, I...

  • Best In-Bed 5th Wheel/Gooseneck Trailer Wiring for a 2015 Chevy Silverado 3500HD
  • Absolutely. Since your 2015 Chevy Silverado 3500 came with a factory installed 7-Way you will be able to tee into the existing harness to install in-bed 5th wheel wiring. You can use # 41157. 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 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.

  • 4-Pole Wiring for 2018 Ford F-150

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.

  • Wiring Harness to Add 4-Way Flat Connector on 2017 Nissan Frontier
  • You can add a 4-flat to your 2017 Nissan Frontier; since you do not have the factory 4-flat you would need the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118525. This will plug into your Nissan Frontier's wiring harness, which is located beneath the rear of the vehicle, along the driver's-side frame rail. I've added links to a video review and install of this harness for you to take a look at.

  • No Power to Brand New 2014 Jeep Grand Cherokee
  • If you have a brand new 2014 Jeep Grand Cherokee and the 7-way does not have power on all of the pins then I would take the Jeep back to the dealer you bought it from and have them fix it. Most likely it's missing relays or they are blown somehow. Either way they should be all functional from the factory so it would be on them to make it work. If this is an aftermarket 7-way you installed on your vehicle then it will need to be reprogrammed. You might check your owners manual for...

  • No Power on Power Wire of 2011 Chevrolet Tahoe
  • The power wire on the trailer connector gets power from the battery via the fuse box. You will want to check the fuse box panel to make sure the wires under the hood are connected to the fuse box (see FAQ). If your 2011 Tahoe does not have a factory 7-way, you will need to install Replacement Multi-Tow 7-Way and 4-Way, part # 30955. This will connect to the wiring above the spare tire on your 2011 Tahoe. I have linked an FAQ on installing a brake controller and 7-way connector on...

  • Troubleshooting GMC Envoy Brake Lights Not Functioning After Connecting Trailer
  • If your Envoy brake lights stopped working along with the trailer's brake lights and you know the vehicle brake circuit fuses are good then the issue is likely to be related to the connector for your wiring harness. The 4-pole and 7-way harnesses for your Envoy, such as # C55384 and # 74682, use a round U.S. Car type connector to join the vehicle wiring. There could be trapped moisture, foreign material, corrosion or a bent pin that is causing loss of the brake light signal. Bad corrosion...

  • 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!

  • 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. I have attached install videos of both harnesses...
