Wiring for towing doesn’t have to mean cutting into your vehicle’s wires. This Curt T-Connector plugs directly into the existing tail light wiring to create a clean 5-pole flat connection. It’s built as a plug-in harness, so there’s no converter box and no need for a factory tow package. Just snap the connectors in place and you’re ready for trailer lights and reverse signal functions.
If you’re towing a boat or trailer that uses a 5-way plug, this harness gives you that extra circuit for the reverse or brake lockout signal. It pairs easily with accessories like a 4-to-5-way adapter when you need to add backup light control. Once you locate and tap into the vehicle’s reverse light wire, you’ll have full 5-pole capability for smoother, safer trailer operation.
Unlike some harnesses that require running a power line to the battery, this one ties straight into the tail light circuits. That makes installation simpler with fewer runs of wire through the vehicle. Everything stays tidy behind the panels, with only the 5-flat lead visible at the hitch when you’re ready to tow.
This is real plug-and-lead trailer hitch wiring made for everyday towing jobs. The connectors are durable and weather-ready, giving you dependable tail light power each time you hook up the trailer. It’s a straightforward wiring solution that keeps things working right without extra parts or guesswork.

Wiring harness is working flawlessly
Wiring Harness was very simple to install in my 2012 GMC Terrain, it arrived on time with no issues.
Very easy to install. Took about 20 minutes. You should use dielectric grease on the wire connections
Great wiring connector that was easy to install - video tutorial was very helpful.
Great Product at a very reasonable price. Easy install. No drilling just bolted right on.
Easy install with wiring harness, hooked right up by plugging in connections and running wire. I used your online video's for how to do it. I am not a mechanic, just determined to save money and I am a 69 year old retired person.
This kit was easy to install. The instructions were a bit vague, I found a video that helped with install.
I purchased a Class III, heavier duty 2" receiver hitch (675lb tongue wt rating) to replace the factory 1-1/4" and a 5-flat, factory wiring t-connector kit. Both fit flawlessly with very good instructions, looked like great quality and had a great price. I ordered on-line on a Sunday and had conformation that the order had shipped before 7:00am Monday! Excellent buying experience and product. I would buy again and recommend to others.
The end results are very simple, the most work is snaking the connectors up to the light housing ..
Would have liked to seen shrink tubing over ground connector...
Worth the money!

Been a Year everything still works as it should BUT I really wish they made a one for a 7 Round !!!! Hint, Hint ETrailer!!!!!

I'm really glad I decided to order from etrailer. I looked at a lot of hitches and your hitch is built just as good as the high priced hitches or better.
Thank you

After using the wiring harness for a year I only have one complaint, the ground pin on the plug broke off. It hasnt effected the operation of the light.
