Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side tail light. You will have to remove the tail light assembly to access this harness.
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.Ordered a trailer wiring harness for my vehicle. I got exactly the right wiring kit with easy to follow instructions. The wiring kit installed easily and worked perfectly for my application.
Patrick, I received the order on time and the product was a quality item and installation was a breeze. Installed the hitch on my jeep and the wiring harness in less than 20 minutes.
Great harness it did what I wanted it to. I was putting a 2nd set of break lights on my Jeep Wrangler with reverse. As you can see from the pictures the install went well and they look great. Customer service was very knowledgeable and helpful

Wire harness is working great
Nice product easy installation and fast delivery.
Great service, very expedient with shipping. Courteous and professional staff. My go to place for trailer parts and vehicle accessories!!
Easy to install, no need to cut wires or break any tab. I bought an « L » bracket and attached it on the Draw Titr hitch and the final look is close to an OEM quality.
Works perfectly
Installed in about an hour on a 2016 Jeep Wrangler willy's wheeler. Perfect fit, steal
Of a deal.
Easy plug and play for my vehicle.
I won't deal with another company!!, you folks as always at least for me, beat the delivery date! The only issue I had and the tech I spoke with said it wasn't possible, was to have a way to have the rear plug work when I tow a trailer with the jeep and not have to switch plugs when I tow the jeep with my motor coach
Great service great product! GREAT COMPANY!!!

We are a dealer of used cars and a ... dealer to order and install hitches from .... The problem is getting the correct wiring for the electrical. I was able to get what I needed from etrailer.com and the delivery was fast. Thanks etrailer.com

CUSTOMER WAS HAPPY WE FIXED THE PROBLEM.
Just like the YouTube video, it was super easy to install. Product description was accurate and harness works great! I'd highly recommend. The only negative I would say is that the information wasn't that detailed when tracking the shipment, but I'm also one of those that likes to know exactly where my shipment is. I would highly recommend Etrailer.com

Great!
Great product
Easy install
Talk about no headache with wiring. This was great for my jeep the only issue I had was finding a drill bit long enough to reach the metal inside the light housing to ground the wire. Other than that everything was super clean and straight to the point. I have a 2010 jeep wrangler sport.

Product has been wonderful no issues at all. I use it a lot and very happy I ordered it.
After one year, wire harness is still holding up and i use my trailer weekly with Lights!
excellent service , excellent products. period!
Good instructions, easily installed. Took me less than 1 hour since you just plug it right into your current light. Running the wires is also easy since their is an opening inside the light area.

As good as new!
Easy install
I installed this as part of adding a trailer controller and 7-pin connector; it was needed for some of the 7-pin wiring. This was explained clearly by the eTrailer order taker, who was very helpful. I've written a review of the whole installation for the Universal Installation Kit (ETBC7), but wanted to add a review for this specific part.
This was the easiest part of the whole installation. Simply remove the tail light on my Wrangler, disconnect the wiring, plug this in between the wire and tail light assembly, attach the ground wire, route the connector to the right place, and it's good to go. There's no way to connect anything wrong, short of forgetting to connect it at all, and everything is sturdy and simple.
Works just like described. Very easy to install and completes your hitch installation.

Amazing. You would think it was factory.
I was very happy with the harness -- it installed quite easily in spite of the fact that I had wired the Jeep up to be towed by my RV years before. This meant that I had already spliced in with wires and diodes, and the cavity behind the tail light was filled with dirt and dried mud from stream crossings made during the past 10 years. Anyway, after getting rid of the dirt and stuff, I found the connector plug shown in the directions and a couple of clicks and everything worked as advertised. I would recommend getting the bracket for mounting the female receptacle at the hitch -- it bolted right up. Also, get some longer zip ties to secure the harness to the frame and keep it away from the muffler.
Installed exactly as video on YouTube showed. Easy to follow instruction in package. Works great! Took longer to read instructions than to install. 5 min to install.

Im still using it today!! Works great!!
I ordered a trailer hitch (Item #75515) and related wiring harness (Item 118416) and bracket for my 2012 Jeep Wrangler. I followed the installation directions in the You-tube video, and was able to install the hitch, wiring harness and bracket without a problem. My local Jeep Dealership wanted $495 for parts and installation. I paid just a little over $100.00 for the parts from etrailer. My order arrived quickly, and I was impressed with the high quality of the parts. Nice job etrailer.
Order received a day after the estimated date. No problem, that's the USPS for you. Installed the harness. The video says about 5 minutes. They are close. The only issue that I had was difficulty finding a place to drill and attach the white ground wire. Basically a plug and play harness. I wish that I had ordered a mounting bracket. The one that is on my 2011 Jeep Wrangler Unlimited is a bit large and the plug is too small to stay put once it is in the bracket. Will manufacture something to hold the plug so that it stays in place.
