Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located at the rear, along the inside of the frame rail on both the driver's and passenger's sides.
Once installation is complete, the 4-way flat 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.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required.After installing a receiver hitch and crawling under my truck trying to scope out a spot to splice into the wiring harness, I noticed convenient couplers in the wiring on both frame rails so I went to the dealer to ask if there was some sort of plug and play trailer wiring that Dodge offered for their Dodge PU's They looked at me sort of dumbfounded and dint even comprehend for the longest time what I was even trying to describe to them. After the 3 explanation of what I wanted they said "Good Idea but no we have nothing like that." Well I wasn't going to give up that easily so I started looking online. I figured if I could not find one I might invent one and make my Millions right!.. Well it didn't take lone before I once again realized someone already beat me to my wonderful idea. So I ordered up a set and the 7 way matching trailer plug to go with it. Renee at etrailer was super helpfull and assured me Id get it in time for Fishing seasons opening week end. UPS had a hick up and it was a day late making me a bit nervous but it still came in time. The product looked of good quality and my only complaint is the tolerances on the plugs don't match the factory plugs very well they are VERY tight and almost impossible to seat in all the way so I hope I don't have issues with them coming loose or the contacts arcing out. But it was definitely the way to go and so much better then hacking in a splice job like most of us have done in our lives. All the lights functioned perfectly on the drivers side first shot but I had to fight with one of the plugs on the passenger side as I stated they did not want to seat all the way in. I didn't see or think to ask Renee about a mounting bracket for the 7 way so I made my own out of some scrap metal I had around my shop. Whole process took me about an hour including making and installing the bracket. Good product, great service from the folks at etrailer and I highly recommend buying form them. They are totally on top of all communication by email to their customers. Kudos to etrailer for building faith in the market place one customer at a time. They have all my future business that's for sure. I'm ready for fishing in the morning! Now what other idea can I come up with dang-it!..lol
Scott H - 04/25/2015Thanks for your follow up and reply. We also recommend brushing off the any dirt, debris, or corrosion that may have built up over time on the connector blades, and prongs, then use a little dielectric grease # 11755 to make ensure a good electrical connection.

Hitch and wiring harness for my 1998 pickup fit perfectly. Order was shipped promptly and actually arrived ahead of projected date. Installation directions were clear and all needed hardware was there. Very happy with etrailer products and service. This was the second hitch I have purchased for my vehicles.
Tom B - 03/16/2021I got my hitch and tail light today. We had it put on my truck in about 25 min. the hardest part was taking the bolt out of the truck frame. It went on as it was made to thank you for a good product. I would buy from you again.
james s - 04/04/2021It’s the best wiring harness I’ve ever bought in my life!
This harness installed without a problem, so much easier to plug the harness connections into the OEM plugs and you are ready to go. Could not be any happier with this set up. When things are simple, cut and dry then everything goes faster like this did. Thanks E trailer.com, will be back in the future.
Works great just wish it had a couple more zip ties included. Easy install took me five minutes, if I need to install one on a different vehicle I would use this same website
It fit perfectly right from the box very easy installation thanks.
Great product with rapid delivery within a couple of days. Literally plug-and-play, this was one of the easiest automotive electrical projects I've ever done, taking about 20 minutes to accomplish. As soon as I finished, I hooked it up to my trailer wiring, and its tail lights and turn signals worked perfectly. Highly recommended.
Works as designed and was easy to install with the support and instructions provided. Would buy this again if I need to wire another of my vehicles.
Jimm - 11/04/2020Easy plug n play wiring for my 97 Ram, nice and clean under the truck zip tied up and out of the way. It would be even easier if the ends were labeled left or right.
Good service. thanks
Gary - 05/24/2021etrailer is always on top of thier game. Only place I use.
The product was an exact fit to my 96 dakota.simply plug n play..moved cross country with uhaul in tow.never worried about lights or blinkers not working. I would highly recommend this wiring adapter opposed to wiring to your factory harness. Thank you etrailer for a quality product.
Perfect fit for my 2003 Dodge Dakota. Took me about 20 minutes to install and it worked perfectly.
Steven - 09/10/2020Connecting the wiring harness went well. I needed two more (longer) plastic zip ties to secure all of the harness out of the way. Testing didn't go quite as well. Everything worked except the left side turn signal. I took the tail light cover off of the pickup. The bulb is a two filament bulb; and both filaments looked fine when held up to a light. I didn't suppose it was possible to plug in a connector turned 180 degrees from correct. I guess that possibility needs to be checked next.
Great product, fast shipping
This was my second order from etrailor, because I was extremely satisfied with my first order. My order arrived two days before the estimated delivery date. I took it out of the box and had it installed in less than ten minutes. It was an exact fit, which didn't require any modifications to my truck.
What an easy way to wire up for a simple trailer lighting. I'll never splice in wiring anymore. The "T-One Vehicle Wiring Harness" is the only way to go!!!
The Wiring Harness was very easy to install! The step-by-step video was the best I've seen to date and gave me the confidence I was ordering the correct part the first time. The etrailer web site is very easy to navigate and extremely user friendly! I've already recommended this site to my friends.
Simple to use, worked great! I wasn't sure if this would fix my issue but it worked :)
The wire harness works great and was exactly what we needed. After a year of hard use, towing 1-2 weekends each month, we have no issues with it.
T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector: arrived a day early, plugged right into my Dakota, checked it with a test light and it all worked! If you want to improve this, add a little electrical grease to protect the contacts and put more than 2 zip ties in - but this is complaining on a high level :-) Very good product and fit! Herb
Part fit my truck perfectly. The custom fit makes it a lot easier than having to figure wires out and splice them. Etrailer.com was the only place I found this custom part for my 1995 Dodge Ram.
Renae - 09/15/2017My son just bought a Popup camper. So we bought a draw-tite class lll frame hitch receiver pn75073, a draw-tite brake controller pn5504, a universal brake control wiring kit pnETBC7, and a custom fit wire harness pn118329 for his truck. It took us a couple of hours to install. The instructions were spot on. He hooked up the camper to his truck, and drove off. Worked as advertised. (hope I get to see him soon!!)
They worked great thanks
