Average Customer Rating:  4.8 out of 5 stars   (485 Customer Reviews)

T-Connector works with fifth-wheel and gooseneck trailers and retains use of your vehicle's factory 7-way connector. It connects your factory 7-pole at the bumper to a new 7-pole in the truck bed. Adapter has a 90-degree angle for tight spaces.


I give a average because I had ordered to fit a 2021 ram 2500. The electrical plugs all match, but I had to drill another hole on the inside of the bed to mount this unit. This truck comes with manufacturers mounting hole that required a larger face plate. The fifth wheel harness was a generic 7 pin harness with ram matched harness plugs installed. Just wished I wouldn’t have had to drill a extra mounting hole.

I got the harness installed, however it was not custom fit for the vehicle. The face plate was too small for the factory mounting hole and I had to make another hole off to the side. The wiring plug Ed in just fine. Only thing that saved things was a spray in bed liner which hid the factory rubber boot where the harness should have fit and didn’t 2021 Ram 2500 Bighorn.

Installation was easy, you will have to purchase a 2" hole saw. Everything fits nicely, and hopefully it will work great. Haven't gotten to use it yet.

Works great, so much easier than the cord hanging over the tailgate. Haven’t had any problems with anything coming loose or getting in the way.

Been very happy with the 90 degree wiring harness over the past year. It saved running the 7 pin connector over the tailgate. Replacing the 7 pin connector with new Junction box helped in cleaning up the mess in the old box. The new 7 pin wiring harness is lighter & more flexible. All 3 products are still working well and have saved me time & functionality.

2015 Chevrolet Silverado 2500

Delivery and order process were very good. Product quality seems pretty low with a significant part of the wiring harness simply wrapped in electrical tape for about 6-8" from both of the connector plugs. Installation instructions were EXTREMELY POOR! The directions call for a 2" diameter hole in the bed and then send the two connectors and the wire all through the hole. IMPOSSIBLE! The small plug is about 2" diameter by itself, plus it has a locking tab on the side that adds about 1/4" to the diameter. On top of that there are the wires to the long plug that also must fit through the hole at the same time. That adds about another 1/4" or more. The net result is you need to create an oblong hole with about 3/4" x 3/4" additional clearance to even begin to fit everything through. NOT easy after the 2" hole is there.... more drilling, filing, cutting, and magic words required. NOT HAPPY!! With a little planning you might be able to use a hole saw and cut an overlapping 1" hole before doing the 2" and that might have worked. Factory should figure this out and tell you the proper hole requirements! Next, the instructions have figure "H" that shows a loose connector plug supposedly in the wiring harness......don't waste your time looking for it 'cause it doesn't exist! A nice picture of the back end of the bumper-mounted 7-pin connector would have made this pretty simple. Figured it out after exhausting my search efforts. Also it might be nice if they included a little dielectric grease to treat the plugs. They will all be hanging in a wet road-salt environment so how long will they last?? Time will tell...


I had to tear out the fifth wheel wiring some professionals installed. My dodge was throwing errors because the way they spliced in allowed water to ground out the trailer wiring. It took me 1 1/2 hours to remove and repair. The system I purchased took less than 15 minutes to install. Thank you for making it so easy. The pictures include what they did and then after new kit installed.


It was very easy to install. The setup takes no time at all. I think I spent more time drilling the hole in my bed than I did on anything else. It works great and I have not had a problem even after a year of using it.


Worked very well for my application, easy and straight forward to install.


Well I drilled an extra hole in my bed thru frame do to lack of correct parts and instructions.

2022 Ram 3500

very easy to connect-fit perfectly on my 2022 Ram 3500 (had to lower tire to release existing wire harness but did not remove tire-unplugged and plugged new unit in-perfect fit-raised tire-done). Only issue found was at the y-end-it is taped to close causing a short y-I cut tape back about 1/2" to open the y and was able to get both ends in the 2" recommended hole.

2019 GMC Sierra 2500

Product comes as discribed fairly simple install the harness with plugs pre installed put the larger plug through the 2” hole you cut first then feed the smaller one
shipping was quick


I received the Reese 5th wheel 16,000 lb slider hitch from etrailer in June 2019; installed it in July 2019. Took around five hours to install the base rail kit and Reese hitch start to finish. So far so good, this heavy duty slider hitch works flawlessly with my F250/fifth wheel combo. It arrived in multiple boxes, had excellent instructions and an operating manual. For myself and other do-it-yourselfers, etrailer provides excellent support and installation videos to help with the install.


Easily installed! Have not tested/ used it yet but so far so good. Installed on my 2019 Ram 2500 gasser.

Highly recommended! Have over 4,000 miles pulling my RV with no issues. Would state that you should ensure you keep it coated with dielectric grease.

The wiring harness arrived within one week of ordering. Drilling the required 2" hole was a simple matter of choosing the location and drilling the hole.

I had to enlarge the upper part of the hole to allow for the wires and plug to pass through, as the 2" diameter wasn't quite enough to accommodate the second plug and the wire together. This enlargement was done with a file. No problem.

The four screws are self tapping, so there's really no need to drill pilot holes unless you just want to make the screws that much easier to put in. A battery powered drill motor was all I needed to drive the screws.

The finished installation is shown in the photos. This turned out to be a nice project, and is part of getting ready for the 5th wheel hitch and trailer.

Excellent product. Well made. Very nice construction. Super easy to install. Literally a "plug and play" affair.

The wiring harness and plug-in greatly exceeded my expectations. I'm glad I made this purchase from


Pulls really well. Very stable and soft ride. Latches and slides nicely. I highly recommend it.

2011 Ford F-250 and F-350 Super Duty

The harness came with everything needed and was very easy to install. Very simple and great product. Works perfect.


Very easy insulation to do


Wiring harness arrived in two days and took about two hours to install . the wiring harness was very we'll built . also the box and packaging was top notch thank you to all


Awesome product very easy to instal I watched videos of other people installing it and a quick glance at the instructions, my son and I were done installing in about 10 min I put the plug in my truck bed almost up to the cab and there was plenty of cord to reach and it made plugging in my Lance Cab Over Camper very nice and easy the things I needed was 2” hole saw and an 8mm socket on an impact to put the plug secure in the bed and some tie wire to tie the cord to the frame of my 2010 DODGE RAM 2500

Thank you


Easy to install, might cut and splice the harness just to eliminate the excess wire and to make it look clean.


This harness is made with great quality and was easy to install myself. One of the best upgrades that I have done to my truck.


Product is well designed and easy to install. Nice heavy wiring! Plugs worked well. I removed the Ford factory 7 wire/ 4 wire trailer plug from the bracket to allow easier unplugging of the factory wiring harness and proper alignment for plugging in the Bargeman wiring harness. The 2" mounting hole the instructions recommend in the inner bed panel is extremely tight to get the second plug through but can be accomplished with patience and careful manipulation. A 2-1/16" hole saw would be better but is a specialized size not available at most consumer outlets. In hindsight, I would file a small notch in the 2" hole to accommodate the connector tab on the second plug and allow easier passage of the plug. The 90 degree molded cable behind the bed connector is a good design feature and should eliminate future connectivity issues you might encounter with a straight harness. Highly recommend!

Still working well. Would purchase again!

Installing this wiring harness was an easy DIY project. Took me about 30 minutes to install in the bed of my truck. Simply drill a 2" hole where you want the plug located, drop in the cords, then plug it into your existing harness. Now, when I plug in my fifth wheel, the cord doesn't hang down behind the tailgate.

2015 Dodge Ram Pickup

Very easy to install, it took me abou 15 minutes on my 2011 Ram 2500. The only "specialty" tool needed was a 2" hole saw. I installed it behind the wheel well instead of in front for easy plug-in while hooking up with the tail gate down, so I had about 3 extra feet I had to zip tie and secure. I only wish it came with two large zip ties. Shipping was great, it arrived 2 days earlier than expected.


Great quality and easy to installed. I have a 2021 ram 3500 with the ram boxes and the 90 degree angle of the connector makes it a easy fit. This is a plug an play item.


Bargman plugs are hands down the best to deal with. Perfect fit and finish.Heavy duty cable and great connectors. Installed on a 2019 ram 3500 for gooseneck and 5th wheel application
