If all you need is running lights, turn, and brake signals, this harness covers the basics with a 4-flat connector. It’s a solid choice for small or utility trailers where you don’t need anything fancy—just a clean, dependable power link from your vehicle to the trailer.
The wiring is built to hold up over time with bonded 16-gauge wires protected by molded rubber insulation. That keeps everything flexible and shielded from road wear and weather. It’s the kind of simple durability that lets you hook up and go without worrying about cracked insulation or loose strands later on.
This harness is made for vehicles that use a 2-wire taillight setup, where the brake and turn signals share the same circuit. You splice it in directly to your existing wiring, making it a straightforward project that gets you towing quickly without extra converters or adapters.
The included mounting bracket gives you a neat, professional look at the back of your vehicle. You can pair it with a no-drill mount if you want to fasten it right to the receiver tube. It keeps the connector easy to reach and out of harm’s way when not in use.
With 60 inches of wire—five full feet—you’ve got enough length to route the harness cleanly from your splice points to your mounting spot. It gives you room to make solid connections and keep everything neatly secured along the way.

They always have what I’m looking for and delivery is always on time.
Very easy to hook up and works perfectl y.
NO PROBLEMS WORKS GREAT EASY INSTALL
Nice design, but the wires need to be about a foot or so longer for a Jeep Grand Cherokee.
Installation was easy and straight forward. It works well.
Very quick shipping and items exactly as described.
Thank You!
Only used the mount that came with it to secure my existing inline 4 plug, mounts easily
I was surprised and disappointed it did not come with a rubber plug cover to protect new terminals, really happy with it besides that,would have given it 5 stars if it had the cover.
Perfect. I've never seen a trailer plug like this. It saves me from dragging my old plug on the ground occasionally
Works as described. Easy to follow installation instructions.
Needed a fast any easy replacement for my trailer wiring for my business and etrailer got it to me within a few days will definitely continue doing business with them thanks again!
Seriously amazing product... I spent more time installing my trailer gate on the trailer than I did installing the wiring harness on my vehicle!! The instructions were clear, and installation was FLAWLESS!!!
I think the hitch will be ok, but I expected the wiring harness to be better. I was looking for one that was tailored to my 2020 Ford Transit T250 and with instructions.
Nice product for upgrading utility tailer connection to vehicle. Love it!
Great item and great value
Sometimes all you need is a simple bracket to hold a connection, instead of having a cable hang down...and this works perfect. I wanted something basic on my S10 that I could mount underneath to the bumper, next to my receiver hitch, to plug my PWC trailer connection into. I had no need for those large 7-way units (nor the space)...WORKED PERFECT!
This connector worked fine. No instructions.
Just remember. The standard connection is:
Yellow = left blinker
Green = right blinker
Brown = brake
White = ground
No problem to attach as I had both a schematic for my vehicle ( so I knew which wires to look for) as well as a 6/12v testing light. With these, the connections were easy.

Actually, I had to change this out for a 5-4 wire conversion harness. The 1999 Chrysler town & country only has the left& right turn signal, tail lights and brake lights on separate wires within the vehicle. So I had to buy the converter bix harness that combines the right turn signal and brake lights into the green wire for the trailer lights to operate properly. I never returned the original as it was only $12. I simply picked up the converter unit at a uhaul. Don’t use this harness if your vehicle doesn’t have the right blinker and brakes combined ie. They are located on separate wires.
it should be 2 feet longer
Great but needs better connectors than the blue plastic ones provided.
good product
good price
Have not installed yet. Just discovered them in the mailbox. It came very quickly after I order it.
Quality product
Received item in a few days after placing the order. Great turnaround time.
The product was fine, and delivery was as well, however I needed the wiring kit FROM the rv to the secondary. My fault

This harness is to be hardwired in. So, you shouldnt have any issues with fit.
