Quickly and easily install a 4-way trailer connector on your Ford F-250 Super Duty 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

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.

Installation was very easy and only took about 15 minutes to hook up and secure wiring on truck.

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.

Works well easy plug and play

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

2018 Dodge Ram Pickup
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.

Fast delivery, and easy to find products. Second trailer hitch I bought from e-trailer. Great products
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.

Working GREAT. Easy to install
by: Jason m07/20/2019
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.

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

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.
by: John05/29/2023
You sent me the wrong wiring kit. It doesnt work on my vehicle.

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.
by: Martin m07/22/2017
Perfect fit. Took 20 minutes to install wire harness and hitch receiver.
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.

- Hidden Hitch & Trailer Wiring For 2019 Jeep Grand CherokeeWe can get your 2019 Jeep Grand Cherokee set up with the Hidden Hitch and 4-way trailer wiring. Just keep in mind the correct 4-way will depend on if your Grand Cherokee has the factory tow package or not; I'll go ahead and list out what you need below: - Hidden Hitch by Draw-Tite Trailer Hitch Receiver # DT26GR - WITHOUT Factory Tow Package: Curt T-Connector Vehicle Wiring Harness # C62VR OR - WITH Factory Tow Package: Curt T-Connector Vehicle Wiring Harness for Factory Tow Package # C55384

If you can get back to me with that information I can try and find a solution for you.
view full answer... - 4-Way Trailer Wiring Harness Recommendation for a 2016 Toyota TundraIf you have a factory trailer wiring connector you could use the part # HM11141835 as a way to install a 4-way easily. Or if you have the factory 7-way connector (which most likely you do), you could use the part # C55384 to splice a 4-way easily into the 7-way wiring harness.
view full answer... - Comparing etrailer and Curt Trailer Hitch for 2023 Dodge DurangoThe Curt # C13182 and etrailer # e98901 are the same hitch with the exception of the finish. Both of these will fit your 2023 Dodge Durango. The Curt has a glossy finish while the etrailer hitch has a matte black finish. I prefer the matte black since it does a better job hiding inevitable dirt and scratches. If the finish isn't a concern then I would choose whichever has a lower price. If you plan to use the hitch for towing you will also need wiring. Assuming you do not have the factory...
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...

view full answer... - How to Hook Up 3rd Brake Lamp on Aftermarket Roll BarA company that installs truck bed camper shells would know more about this, but I'd be happy to provide what help I can. A T-Connector like # C55384 wouldn't work because the brake lamp signal is carried on the same circuit as the turn signals which would cause the 3rd brake lamp to blink with the turn signal. You'll have better luck finding the circuit that feeds the CHMSL or 3rd brake lamp. The easiest way to do this is to gently remove the existing 3rd brake lamp and use a circuit...
view full answer... - 4- or 7-Way Trailer Side Connector to Match Factory Tow Package on 2012 Ram 2500Your 2012 Ram 2500 should have both a 4-Way flat and 7-Way trailer connector at the back. If the trailer just needs a connector for the lights then you would install a trailer side 4-Way such as # A35W42B. Or for a shorter one use # 18004. I have linked some videos of these parts for you. If the trailer requires not just lights but also 12 volt power, electric brakes, and auxiliary power or reverse lights then you would want to install # H20046 or if just the connector is needed # PK12706....

This is a Class lll hitch and has a 2 inch receiver opening. I have attached a link to an installation video for this trailer hitch on a 2011 Grand Cherokee you can check out. The hitch is rated with a maximum trailer weight of 5,000 lbs and a maximum tongue weight of 500 lbs. You will want to check your owner's manual or with your dealership to make sure you do not exceed the towing or tongue weight...

If your wiring has been on the vehicle and has suddenly stopped working then the likely causes are blown fuses, bad relays or corrosion in the connectors. First, make sure that your...
view full answer... - Trailer Wiring Harness for 2001 Ford Ranger 3.0LThe 4-pole wiring harness kit you referenced, Curt # C55510, is not a fit for your 2001 Ford Ranger but we do have similar wiring kits that will work fine for you. You can see all wiring harness products for your Ranger on the page I linked for you. If the truck does not have the tow package you can add a 4-pole harness # 118344 which simply plugs in at your tail lights. If the truck does have the tow package then for a replacement 4-pole you can use # C55384 or for a 4-pole/7-way combination...
view full answer... - Will the Curt T-Connector Harness Work On a 2020 Jeep Grand Cherokee Without Tow PackageThe Curt T-Connector Vehicle Wiring Harness part # C55384 is a fit for a 2020 Jeep Grand Cherokee. That said, although the plug needed to use this will be present on all models, only those equipped with the factory tow package will have the circuits active. Therefore, if you wanted to use this you'd need to take the vehicle to the dealer for programming. This can be expensive so a much better option would be to use the T-One Vehicle Wiring Harness part # 118727 which is for models without...

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... - Trailer Wiring Adapter for 2019 Ford F-250 to Provide Lighting for Headache RackUsually headache racks that have taillight functions like what you mentioned use a standard 4-way trailer connector to power the lights so your best solution is the part # C55384 which plugs in line with the 7-way you have now and provides a 4-way and harness you can use for the headache rack and also leaves the 7-way totally functional. You'll want a 4-way extension too with part # HM47114.

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... - Recommended Ball Mount for a 2021 Chevy TahoeFor your 2021 Chevy Tahoe, I recommend the Curt Class III Ball Mount with 2" Ball item # C45056. This ball mount has a 4" drop, a 2" rise and a 7,500 lbs capacity. I have linked a review video below that will go over the functions of this ball mount. I also recommend purchasing the etrailer Hitch Receiver Lock item # e98881. This locking hitch pin will secure your ball mount from theft.

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.

view full answer... - Easy Way to Wire Lighting of B&W Headache Rack to Truck Trailer WiringThe B&W Custom Headache Rack w/ LED Brake, Turn, Tail Lights # BWPUCP7500WA that you referenced uses standard 4-way wiring to power the lighting functions. So what you can do is install the # C55384 behind the 7-way of your truck and then wire a 4-way part # HM38134 to the headache rack and you'd have a very easy to install wiring setup.
view full answer... - Recommended Hitch and Wiring for 2020 Ford Explorer without Factory Towing PackageThe Curt # CU78FR is the correct hitch for your 2020 Ford Explorer and the powder coating on Curt hitches is a bit thicker, so it's going to help protect the hitch from scratches better than other hitches. For wiring, the Curt # C55384 is designed for Ford Explorers with the factory towing package, so it's likely that this 2020 Explorer doesn't have this towing package. Instead of the # C55384 you'll want to use the # C56093 which comes with all of the fuses and parts needed to install...

This hitch has gotten universal praise from our customers, with over 450 reviews giving it a nearly unanimous 5 stars.

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.
