Well made and fits perfectly

I bought this 4 way flat harness to replace one that was wearing out on the trailer. it was easy to hook up. I dont think it came with instructions of which wire to hook up (i just paid attention to what was already hooked up and how) but its not rocket science to figure out. Wish the 12" wire was longer BUT it got the job done with some extensions, but this was an older trailer so a newer one would probably be fine with 12" of wire.


Exactly what I needed to fix my trailer lights. Good quality. Plenty of wire to replace as far back as you need to go.

Good price, solid.

Easy to install and work as expected

Fit great, exactly what I needed

Great plug, I have never bought a bad Atwood product.
