If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Ram ProMaster 1500, 2500 and 3500 (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

Works without any issues.
It's always a pain to remove trim. Half of the work is getting the trim off and ready to run the wires. I recommend getting 1/4" wire loom for the wire run between the lights. There's lots of sharp corners. You will need wire crim tool, wire stripper to do the wiring, and electrical tape. There's a few good youtube videos that walk you through the installation. Instructions pictures are pretty terrible, but the videos show everything. Overall, it does what it needs to do.

not the quality I expected, but ok
Worked great, directions are not as good as I would have liked, and one trailer side light seems to be barely on all the time. Also this wiring is too short for anything, but the standard height model, I had to extend going over the back doors to the passenger side. This is for a Ram Promaster and they don't specify how to bring the wiring harness to the hitch, someone even suggested sticking it out of the door?!?!? There is a rubber grommet under the rear bumper on the driver side, remove that and route your wiring through it. The lights do work very well though, very bright. I soldered all of my connections.

It works on a 2019 2500 Promaster
It works, Chrysler wanted $450 for their connector

quick install, but functionally flawed
Pros:- Reasonably clear instructions with color photos.- Installation took ~45 min.- Kit included everything down to zip ties.Cons:I tried different sequences of switching off my Promaster lights, but could never get the U-Haul 4x8 trailer tail lights to go out unless I unplugged the wiring kit. Had I not noticed this there's a decent chance I would have woken up with a dead battery in the middle of the UT desert.

Watch the YouTube installation video
Very well designed. After watching the installation video I didn't even need to look at the instructions.

Another great Curt Product
I have been installing hitches, wiring, and brake controllers for over 12 years and have used nearly every manufacturer out there. Curt by far has the best price/product/install combo. This wiring kit is no exception. Install time and difficulty is a bit higher but this is more due to Dodge and the way they made their vehicle rather than Curt. The kit is thorough and has everything you need.

The mounting tape failed.
The unit works well but the mounting tape failed because the inner foam let go.

It does the job
Installation is straightforward and it works well.

Exactly as described.
Purchased this harness to go with the hitch from the same company. A bit of a challenge if you lack electrical skills so a good idea to get assistance in that regard. Also, YouTube videos offer great installation pointers. Good heavy wire, no skimping on that. Overall, a quality product.

Seems to work greatDidn’t realize when I ordered it that the trailer end connection part was made to just hang out the back door. I thought that it would somehow be made to hook on the exterior of the van somehow
