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.

Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located beneath your vehicle, along the driver's-side frame rail.
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.

Fit perfectly for my 1995 f150 single cab rwd long bed 4.9l, after 1 year still holding on strong and would highly recommend
Thanks again for having what I needed and for the fast processing. Had to wait for a day of rain but, had it in the following day. Plugged it in and tested it. Good to go. Now I can pull a trailer.
You are the best!
3 time ordering and always good service.
Website was best i have seen, great detail, product was easy-breezey to install, only trouble was cleaning dirt from under truck to keep out of my eyes, should of worn safety glasses
Wow. Works as advertised. Easy. Trailer lights work and took less than 5 minutes
I installed the trailer lights connecter adapter into the wiring harness at the rear of my 1996 Ford F-150 today. The wires were exactly were the instructions said they would be located. With some effort after engaging the relief clip I was able to pull apart the wiring harness. Installing the trailer light connecter adapter went easily. I only had to pull lose one wiring harness holder from the frame to give more slack in the wiring harness to make room for adapter to fit. After installation I tested the lights and everything (turns signals, tail lights and brake lights) all worked properly. The quality of the adapter looks great just like it was a factory original part. I expect to have properly functioning trailer lights for a long time now. Thanks.
This product is just what i needed to connect to my trailer harness. No cutting or splicing, so you get no corrosion. Just unplug truck wire harness plug in this in and you are ready to connect trailer lights. great product . couldn't find this in stores either. etrailer.com saved me lots of time. easy ordering and quick shipping only a couple days and I had the product. Thank You.

Im having trouble with the ground wire trailer lights intermitently work or dont work or some work and not others after investigating found the insulation on the ground wire coming from the product i purchased had come out of the plug at the trailer connection causing the wire to fray and corrode and a few strands of the wire have broke. i have had to add a seperate ground wire to help .

The products I ordered were received timely, installed easily, and were made of quality material. I look forward to years of quality service from these items. The service staff members at etrailer are kind, courteous, knowledgeable. I would highly recommend etrailer for your trailering needs. The only recommendation for improvement would be to tweek your on-line order tracking system. I received the items before I could track their whereabouts through the on-line order tracking system. Great site for quick reliable service!

The product worked perfect for me during the period I owned the vehicle. Sold the vehicle a few months ago.
A great way to update a trailer plug. No more tapped wire connections.
My taillights didn't work anymore and now they do.
I will recommend this to others.

It works great and I recommend it to any of my friends that pull trailers.
Good product, fit was perfect and easy to install
Product works great and installed perfectly just as the instructions said it would. Install only took about 5 minutes and was super simple. I didn't need any tools except for a Flathead screwdriver in order to release the old crappy clips that were on my truck wiring harness. My truck didn't have a trailer light hookup when I bought it so this item worked perfectly for what I needed and was way easier than splicing wires and making my own. Defiantly worth it and would buy again if I buy another truck and it doesn't have trailer lights.
Perfect fit for my 1993 Ford F-150. Easily installed with no hassle. Works perfect and solved the trailer light issue.

Still working perfectly. No issues whatsoever!!!!
A waste of money and most important my time, Put it in my old bronco to keep the original wiring
Super easy to install just unplug and plug the T and good to go. never use my bronco to pull trailers had it only as an emergency so on December 2018 I need to pull a trailer for my kids quads the wire didn't work, ended up heading to Autozone to buy a universal and spacing my wires in my bronco. Really disappointed with your product.
Having an older truck that’s been temperamental about the rear lights lately, I was very pleased that this plugged straight in and worked right away with no disruptions. I was dreading replacing a previous owners abomination of electrical wizardry. All I had to do was snip the old 4 pin wiring away and clean it up so as not to short anything out, then plug in the adapter to the truck’s wiring harness and to the new 7/4 pin plug and I was done.
Product #118316 T connector to factory lights on a 1995 Ford F-350 I was having trouble with my trailer lights so a friend of mine told me to buy a T connector, well I tried all of the normal places and they didnt have them, then a saw a video on U Tube and the guy was saying these little T Connectors from etrailer work great and are so simple to use, well he was not fooling I ordered one and it came sooner then expected plugged it in to my truck lights and boom all of the trailer lights work like a charm. Do not fool around with other retailers junk, Buy the right part the first time BUY etrailer you cannot go wrong.
Very satisfied Stacy was really helpful,and harness works great good experience
This thing is awesome! Took a grand total of 5 minutes to install and route to my bumper where it was needed. Don't forget to get a few zip ties to secure the wire where it needs to be!

Still working great! Im surprised the little plastic cap over the end is still in tact, but it is!
Easiest wiring install in my life. Unplug one connection and insert the T connection. Plug it back in and voila! Had the bracket to install on the rear bumper, found a spot, drilled a couple holes and it’s there forever now. Couple tie wraps to clean it up and you’re done in 10 minutes.
Works perfectly and should last as long as the truck does.
Fit perfectly, no problems. Used with 4 pole to 7 pole connector 30717 on 1995 F 350. Truck had a pigtail for a brake controller wire, but deadheads at firewall. Ran separate wires to pre plumbed 30717 to connect brake contoller
Just bought a trailer. Figured I would have to spend a lot of time splicing and wiring underneath my truck. Found this website and was able to find the part I needed quickly. There was even an installation instruction video. Received the part in three days and had it installed and working in less than 5 minutes. Thank you etrailer.
A perfect fit as guaranteed. After washing the years of crud off the factory harness of my 1994 Ford Supercab the plug-in adapter fit perfectly into place and by boat trailer lights worked beautifully.
The wiring harness was going to be delivered by UPS on Tuesday but came in regular mail 3 day early. The harness seems well made. Very easy to install, took around 3 minutes. Worth every cent. I'm very happy with the wiring harness. I might order a hitch and wiring harness for our Edge Limited next.
I was very happy with the products and service I received from this company. The product was exactly what I ordered and was delivered in a timely manner. I've already installed them on my trucks. I will definitely use them again in the future
After a year the wiring harness is dependably working and I would highly recommend etrailer to everyone.
