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.
Tail Light Converter
A tail light converter is built into this T-One connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of your trailer. The tail light converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.

The wiring harness was easily installed and has functioned perfectly for a year now.
Brent W - 12/18/2021One year ago I bought this wiring harness for my 1999 Ford Ranger XLT after trying to repair and fix the pigtails that the previous owner of my vehicle installed. After installing this system, I noticed an immediate benefit of having it plug into the existing factory wiring harness for the lights everything works phenomenal and perfectly every single day that I hook up my trailer. In the year that I've had it I have not had to troubleshoot lighting issues especially with your running lights on no issues whatsoever everything runs perfect! don't be like me and buy a bunch of other stuff like additional pigtails trying to fix what someone else has done just buy this system it's worth the money and go for it! I was so confident in this system that I just installed wiring and a hitch on a 2018 Ford Transit t250 and that system is phenomenal too!
So to start, I bought this 3 years ago & installed it on my 99 ford ranger after giving up on the pigtails that were previously used as trailer lights. So, the system is designed to either run normal or just stop in the case that something goes haywire in the module. This is what happened in the old system module. Therefore I bought a new one & my trailer lights are running like new again! I figure since I'm pulling a trailer 8 months a year, spending ~$40 every 3 years is not a bad deal. It's easy enough to install, lowet your spare tire. Locate the factory wire harness (usually up behind hitch & behind the bumper) disconnect lights, insert the module with addition of silicone paste, snap together, put it back in general area, route your wire & raise your spare tire. 15 mins max. & done! Super easy!
Plug and play. Can't beat it. I bought one of these for my 92 Ford Ranger and one for my 96 Ford Ranger. 2 different part numbers. Simple as unplugging the harness where the bed attaches to the frame at the rear and plug this in between the two plug halves. EZ-PZ. I have used etrailer before and i will use them again if i need to.
Very easy to install tried all the lights everything worked perfect very pleased with this product IF I add a trailer hitch to another vehicle I will use this type of connection no more splicing wires and taping them up GREAT PRODUCT
Worked great, and just a couple minutes to install!
Quick easy install on Ranger pickup. Everything fit.
Great product. This is easier to install before the hitch.
Perfect fit
Roy - 02/16/2022easy to fit in electrical harness on my truck and seems plenty long enough for my use.
Perfect fit
I installed this on a 1996 Ranger. I removed the rearmost bumper mounting bolt on each side and then loosened the other two. This allowed the bumper to drop down far enough to easily access the wiring. At that point you unplug the factor harness and plug in the trailer wiring. I drilled one hole behind the license plate to hold the wiring harness in place and the installation was complete.
Tom N - 05/28/2015Product arrived on-time and thanks to the helpful instructions, I was able to install this wiring harness in a matter of minutes. My son is out using the truck w/trailer to mow lawns or I would take a picture of the installed harness. I am very satisfied with the product.
Ray F - 09/02/2017We bought aTekonsha custom fit vehicle wiring for wiring up the trailer and it was perfect. Wiring a trailer has never been so easy, we made a great choice. etrailer is very good to work with and they deliver fast. I wouldn't hesitate to use them again.
L K - 07/07/2020Plugged right into my 1994 Ford Ranger wiring harness and worked great. I use my trailer all the time and it is still working great!
Product was as described. It plugged right into the original harness everything thing is great. I went cheap on shipping and still had the harness in 4 days. I will not go anywhere else for trailer parts. Awesome job
Scott - 11/29/2016I was able to install the part that I bought on my truck, but I didn't realize that the 4-pole flat output doesn't have a wire for a brake light, and I need a wire for a brake light. Do you have any suggestions for a supplementary/replacement part that I could buy from you guys that would include a wire for a brake light? I have a 1997 Ford Ranger, and the T portion of the product that I bought works just fine - the only issue is that the brake light wire is lost somehow in the conversion.
Mike L - 02/27/2019Awesome hitch wiring for my ford ranger. I only had to unplug current wiring and plug in this adaptor and that was all. I would like to let everyone know that if your ford ranger (mine is 1994) needs wiring harness for a hitch this is the exact fit and is still working 1 year later.
Couldn't be happier with the wiring harness. It plugged directly into the wiring harness on the truck and had enough length to route it along the frame and secure it with wire ties in several places. The converter came with self-stick adhesive which made mounting a breeze, although I also secured it with a small bolt through the mounting hole on the converter. During the installation, I used 1/2 inch plastic ribbed wire conduit to protect the wiring harness from chaffing, although it is not necessary. I installed it on a 1999 Ford Ranger, which has separate turn signal lamps from the tail/brake lamps. If you have a similar vehicle, I highly recommend this product. Also shipping was extremely fast.
I ordered a trailer wiring harness for my Ford Ranger. It arrived several days earlier than scheduled, which is always appreciated! Installation was very easy, took only about 10 minutes. It plugged right into the factory wiring harness. A quick check with the voltmeter to verify everything works, which it does, and I'm ready to tow! Thanks e-trailer!
Great product thus far. The installation was simple (the connector is right above the back of the bumper), and between the supplied zip tie and the adhesive backing on the plastic box, it was easy to mount securely to the back of the bumper mount structure. Now I just need to figure out how to securely and cleanly hide away the wiring while it's not in use.
The whole experience with etrailer has been great so far, btw. Everything I ordered shipped in sturdy boxes, was well packaged, and shipped quickly.
This product fit the factory wiring harness as advertised. Made adding the trailer wiring connection very simple without creating new problems in the vehicles wiring harness. I would buy this product again if I needed to add trailer wiring to another vehicle.
the product was as described, fit well no problems, needs a better way to attach connector to bumper. still plug and play.
phillip - 09/14/2016I'll tell ya what, this made wiring for my trailer a no-brainer. I found the connection on the rear underside of my truck, separated, and inserted the wiring harness, and i was off and running! (just had to make sure everything was secure).
thanks guys, custom harness makes this easy for someone who is not so truck or wire savvy.
