Great 4 to 7 pin adapter
Great price for the converter. Well-made and works as advertised. Needed this to connect my 7-pin boat trailer to my 4-pin SUV, and this worked perfectly.

Works great and great bargain!
Great bargain. Apparently this is not a typical combo for an adapter. Had a hard time finding one in stores. Found one at Tractor supply, but they wanted $55 for it! Glad I looked here and found it so cheap. Works great!

Works exactly as expected
Works perfectly.I will say that I didn’t realize until later that the 4 pin connector powers only lights. We are now planning to rewire our car for a 7 pin so that brakes and DC battery charging also work while towing.If you need only lights, buy this!

Great 7 pin to 4 pin adapter!
Worked perfect. Didn't have to rewire the plug on the trailer and can use the 7 pin for the truck and the 4 pin for the car.

Towing Upgrade
Good plug and play option to allow towing of newer trailers. Fits my 2005 Tundra SR5 access cab.

Mates Older Vehicle with Newer Trailer
Nice unit if you are trying to use a newer trailer (Round 7-pin flat blade style connector) with an older vehicle (4 prong round pin connector). You WILL GET your trailer running lights, brake lights, and left/right turn signals. You WILL NOT GET electric braking or Reverse lights though.

Great so far!
I've only used it once, but I attached it to my trailer with zip ties and it works perfectly on our truck. We don't have a 7 pin on the towing truck, and we don't need to charge our camper as we drive, so this adapter is spot on for our use! I'll update if any issues, but so far so good!
