This adaptor works well for us. When we narrow a neighbour's trailer to tow a friends unit, we are flexible regarding lights connection.

This seems well made, so no quality issues. I had hoped to plug this into a vehicle harness that I added to vehicle that I am towing behind my motorhome. Both had male connections, so I had to chop and splice wires. Also the bracket is very tall. I ended up ordering another shorter bracket.

We were skeptical at first but this worked flawlessly the first attempt. 4-pin wired SUV (GM) pulling a large 7-pin wired hybrid trailer (Jayco). The Wireless brake controller worked with this adapter too. Definitely a more cost-effective option than getting your vehicle rewired. Would definitely recommend!

Very happy with the quality of this extension cord. My existing trailer cord was a little too tight on turns so by adding this cord it has relieved my worries. card was delivered to my door in less than a week.

Used it to connect my dad's 1998 gmc truck and his welder trailer adapters together. Easy to connect.

did exactly as it should. Can either plug and go or mount it with the included bracket.

I could not find this specific product in any store. I seen it on amazon and had my doubts if it would work. I was not disappointed, worth the money, it got here a week before the estimated delivery date too.

I have had my car hauler for many years and it has the 6 round pin connector. They work great but I didn't swap out the harness off my last truck.This came with a bracket that I figured I would need since my truck bumper only had the 4 holes for the 7 blade type connector. Nope! I turned it diagonally and the holes lined right up. Must be clean livin. :)The four pin connected perfectly as well.
