Installation
This custom-fit T-connector plugs into your Chevrolet Silverado 3500'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 3500, 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.

This product was exactly what was portrayed on line. Wiring harness was very simple to install and works extremely well.
by: Dan 11/15/2023
Yup. Still works after a year in operation. The only thing I am unhappy with is my vehicle thinks there is always a trailer connected and the backup sensors and side sensors are automatically disabled.
by: Mcrae11/18/2023
When I finally installed it about 3 months ago, the plug in connectors did not match what I had on my truck. I ended up just cutting them off and splicing them into the connector from my truck

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.
by: Virgil06/06/2022
Was exactly as stated in description. Just unplugged old plug and plugged in new one. I had two plugs to replace and added an extra "T" plug for another 4 prong. It only took less than 15 minutes to install all 3. Customer service is wonderful. Everything I have bought from ETrailer is top notch and delivered on time or earlier.

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!!

I wanted to ask if your 2001 Chevy Silverado came with the tow package? Did you already have a factory seven way? If not, the part # C59236 would be the better fit.

Can you please provide a picture of the underside where the plug is supposed to be located? For vehicles with the factory tow package; your install may require additional components or may be used as a replacement harness.

Easy instructions, installation was a breeze. Very important to torque bolts down to spec. Also will need to have dealer “flash” vehicle to activate trailer lights. 5 stars

This harness is meant to be used for a 2023 Ford Explorer that has a factory seven way to add on a four flat. If you do not have the factory seven way, then you will want to use part # C56093 instead.

This is a great vehicle to trailer wiring harness just plug it in and you're ready to go and that's all they are to it plug and go and I recommend it.

by: Rod A12/30/2021
This T-Connector is working great. Installation was simple. It was truly plug n play.
I used it to connect a LED light bar on back of truck; allowed me to install the light without using the existing trailer connector, so it is still available.

Its been a year since I installed the T-Connector. And it is still working like brand new no issues with this connector. Provides a great convenience not having the share the OEM trailer slot.

- Does Curt T-Connector C55384 Fit A 2008 Chevrolet Trailblazer LT with Factory Tow Package?The Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector # C55384 you were looking at is confirmed to fit your 2008 Chevrolet Trailblazer LT, and will require you to unplug the US Car connector from the back of the 7-way connector. The # C55384 will install in-between your 7-way connector and factory tow package wiring. I included a video of the # C55384 for you to take a look at.
view full answer... - Hitch Receiver and Ball Mount Kit for 2021 Chevrolet Silverado 1500I would be happy to help you set your 2021 Chevrolet Silverado 1500 up for towing. Lets start with a hitch receiver. I recommend the Curt Trailer Hitch Receiver item # C59UR. This is a custom fit 2" class IV hitch receiver with a maximum gross trailer weight of 10,000 lbs and tongue weight of 1,000 lbs. This receiver bolts directly to your frame and requires no drilling. I have linked an installation video and picture for you so you can follow the steps and see the final product. To complete...

- Is Reverse Light Circuit Present on Curt 7-Way to 4-Way # C55384The reverse light circuit is present on the wiring that runs between just the two round connectors of the part # C55384 that you referenced. It's the wire that feeds the center pin.
view full answer... - Wiring Dome Light and Third Brake Light on a Camper Shell on a 2009 GMC Sierra SLEThe 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 is...

- Troubleshooting GMC Envoy Brake Lights Not Functioning After Connecting TrailerIf 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...
view full answer... - Trailer Wiring Harness for a 2001 Toyota SiennaThere 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.
view full answer... - Troubleshooting Trailer Running Lights That Dont Work With Curt # C55384 on a 2018 Grand CherokeeIf the running lights don't work on your trailer then there are a few different things to check. Typically light malfunctions are the result of a bad ground so I definitely recommend starting off by checking the grounds on your trailer running light circuit to ensure they are all securely connected to a clean, bare-metal surface. After checking your grounds if you are still having problems then it is best to use a circuit tester like part # PTW2992 to test the Curt T-Connector # C55384...
view full answer... - Towing Capacity of 2004 Chevy Silverado and Recommended Hitch for Towing Enclosed TrailerIn order to find the correct towing capacity for your 2004 Chevy Silverado, you're going to want to consult with the owner's manual; from what I was able to find, you'll be able to tow between 7500 and 9100-lbs depending on the exact model and specs on your truck. If the Silverado is four-wheel drive and has a 3.73:1 axle ratio, the capacity is 7,800 lbs (extended cab) or 8,200 lbs (regular cab); if it is four-wheel drive and has a 4.10:1 axle ratio the towing capacity is 8,800 lbs (extended...
view full answer... - Tail Light and License Plate Solution for Transporting Covered BikesThe best solution we have is to use the Thule License Plate Holder # TH35JV for the license plate part of your problem and then adding magnetic towing lights like the Wireless Hopkins # C6304 (you need 8 AA batteries # DU58QR) or Optronics # TL21RK so your tail lights are still visible. Since your Swagman XC2 Bike Rack # S64650 will be covered with the bag you'll need to get creative with the mounting straps for the Thule License Plate Holder but it's the best option for your application.

First you will be able to use the Curt T-Connector Vehicle Wiring Harness # C55384 to tee into your factory trailer wiring to get the additional 4-way for the light bar. Then you will be able to use the Roadmaster Universal Hy-Power Diode Wiring Kit # RM-152 to splice another set of diodes...
view full answer... - Will the Curt T-Connector Vehicle Wiring Harness C55384 Fit a 2019 Ford F-150The Curt T-Connector Vehicle Wiring Harness part # C55384 plug into an industry standard connector so it will work just fine on a 2019 Ford F-150. In regards to the prompt you see on our website, this simply means we don't have it listed in the fit guide not that it does not work. Sorry for the confusion.
view full answer... - Wiring Harness for 2015 Jeep Grand Cherokee with Factory Tow PackageThe wiring harness you'll need for your 2015 Jeep Grand Cherokee with factory tow package is the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector # C55384. This will plug directly into 7-way OEM tow package wiring harness. I've added links to a review video and install of this harness for you to take a look at.
view full answer... - Recommended Trailer Hitch And Wiring For A 2023 Ford Explorer For a 2023 Ford Explorer you would need the Curt T-Connector Vehicle Wiring Harness # C56093 if you did not have the factory trailer connector. If you did you would instead need the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package # C55384. For the trailer hitch I recommend the Curt Trailer Hitch Receiver # CU78FR. I've attached some video below that will help walk you through the installation process of these products if you plan to do them yourself.
view full answer... - How to Use Ford 7-Way # 118243 and Have a 4-Way HarnessI have a solution for you, but they don't sell just the harness of the # 118243 or a version that also includes a 4-way. Instead you would want to go with the # 118243 and then use the part # 74682 instead of the included 7-way. Or go with the # 118243 and then also install the # C55384 to install inline with the 7-way.
view full answer... - Recommended Trailer Hitch for 2013 Jeep Grand CherokeeI have a solution for you, but the Curt # C13900 is a multi-fit hitch, so it would likely take some modifications and drilling for installation on your 2013 Jeep Grand Cherokee. For this reason I recommend instead using the Curt # C13065 which is a custom fit for your Grand Cherokee, so that means no drilling and an easy, bolt on installation to save you time and hassle. This hitch is also a Class III receiver like the C13900 and uses a concealed cross-tube that really gives it a great...

This will plug inline with the 7-way to provide you with a 4-way.
view full answer... - Trailer Wiring Harness that Does Not Require Splicing for a 2016 Chevy ColoradoI 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!
view full answer... - How to Add Additional 4-Way Connection to a 2022 Ford F-350 Super DutyI've got a quick and easy solution for you with the Curt T-Connector Vehicle Wiring Harness # C55384. This tees in behind your current 4-Way/7-Way using the US CAR connection and gives you an additional 4-Way that you'll be able to use the same time your 7-Way is being used. I recommend picking up the Brophy Mounting Bracket # BK4F and N-Drill Mounting Bracket # 18136 so the additional 4-Way can be held in a place that has easy access.
view full answer... - Troubleshooting Why Taillights And Light Bar Permanently Stay On After Installing Harness # C55384It sounds like the circuit is being powered when it is not supposed to be due to a wiring fault. To resolve I would recommend tracing the aux power chord that is routed to your tail lights using The Hook Probe Circuit Tester # PTW2993. Using this tester will identify any shorts in the circuits, or fuses on your 2014 Chevrolet Silverado 1500. If the voltage checks out fine you could of just got a bad wiring harness but it really sounds that there could be a short on your AUX power chord....
view full answer... - Trailer Running Lamp Circuit of 2018 Chevy 2500 Not Working At Trailer ConnectorLets begin with the non-functional trailer running lamp circuit. I'd suspect a fuse in the engine compartment fuse block in location # 15. Replace the fuse but before plugging the trailer back in, you'll want to closely examine the running lamp circuit on the trailer and its trailer connector to locate the short and repair it or you continually blow fuses. This could be an intermittent problem caused by a loose connection or some cracked or worn wire insulation on the wire in the running...

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

This will plug in behind your tail lights, providing you with a 4-way to power the lights on your boat trailer. If you do have a factory trailer connector you need the # C55384 instead.

This custom harness will plug right into the built-in harness located behind the rear bumper. You will simply plug the harness in-line with the existing 7-Way.

view full answer... - How to Wire 3rd Brake Light on 2022 Toyota Tacoma ARE Truck CapThe easiest way to accomplish what you're wanting to do is by using the 3rd Brake Light Logic Module # PP20-702 to isolate that brake signal. Then you can either run your wiring from below your truck or you can use a tee-in connector like the Curt # C55384 so you can get that 4-Way connector and those functions closer to your ARE truck cap. You will need to ground one of the wires from your truck cap, and then the power wire will connect to the output wire of this module.

1 year & still works great, very easy plug & play setup. I recommend putting a small amount of white lithium grease on those connecting, helps protest against rusting.
