I used this Oyviny 4-pin wiring harness to rewire my utility trailer, and it's been solid so far. The 22ft length was perfect for my setup, and the 18AWG wire feels durable. Installation was straightforward, which is always a plus!

Decent but had one hiccup
This wiring harness works well for my trailer, but I did have a bit of trouble with the installation instructions — could've been clearer. The 22ft length is great though, and I appreciate the quality of the 18AWG wires.

Sturdy and reliable wiring!
I replaced the old wiring on my trailer with this Oyviny harness and it’s been fantastic. Nice sturdy 18AWG wires and the 22ft length was just what I needed. My lights are working perfectly now!

Average product, nothing special
It’s an okay wiring harness. It does the job, but it doesn’t feel super high quality. The length is nice at 22ft, but I just expected a bit more for the price. It’s functional but not impressive.
