This harness skips the messy part of trailer wiring. It plugs directly into the factory connectors behind the tail lights, so you don’t have to cut, splice, or guess at wire functions. It’s built as a custom fit and gives you a clean install that blends right in with existing wiring.
Once it’s plugged in, the 4-flat connector provides running lights, turn signals, and brake lights to your trailer. It’s the standard setup for most small trailers and utility haulers, giving you everything needed for basic towing.
There’s no separate power module or converter to mount with this harness. Curt tested it and found no circuit protection was needed for proper function. That means fewer parts to deal with and a simpler install that keeps things tidy behind the panels.
Because it uses vehicle-specific plugs, the harness snaps right in where it should. The fit feels factory, and you can route it through existing openings or grommets for a clean look. Once connected, it’s ready for the trailer—no extra adapters or hardwiring required.

easy peasy
Excellent item, priced right and delivered quickly.. and great communication. This kit was fully assembled was very easy to install - and fit the 2006 Buick Lacrosse perfectly.
Just what I needed to complete the hitch installation. Thank you
Hitch and wiring were in stock, unlike a competitor who's products were on backorder. Shipped in a timely fashion!
No splicing of wires, just remove taillights and plug in and ready to go
I received the trailer hitch & wiring kit for my 2008 Buick LaCrosse in a very timely manner. The installed very easily, quite like the video showed. I installed the wiring kit today, & it fit perfectly and works as it should. Thank you.
Instructions weren't quite accurate - there was more disassembly required to get to the tail light connectors than the instructions indicated. Also, there is a ground wire that the instructions did not indicate where/how to attach. Kit was complete, and was easy to install (installation made sense - just pointing out that the instructions could be more accurate). For the record I installed this on a 2006 Buick Lacrosse CX.
This is the second one I have purchased from you. The first was excellent, easy to install and I'm sure this one will be also. To make it even easier I ordered the wiring harness also. I will have to tell you later how it went since I just received it. I was surprised how fast it came. Thanks

Instructions were good but wiring was not easy to install. Took a lot more time than I would have ever thought. After installation everything has been working fine
