the part was used to connect the standard 2011 antenna in my Tacoma to a 2013 Entune head unit with a new style connector. It worked fine and arrived faster than expected.

Pros: connected and worked.

Cons: none

Worked perfectly for installing a 2014 Tacoma Radio in my 2007

Pros: Just what I needed to attach my 2007 factory antenna to the 2014 antenna port

Cons: Found out later that it came in a kit with the USB port cable

This adapter harness, along with the Metra 40-LX11 Antenna Adapter harness, worked interfacing my JVC HD radio receiver to my stock radio. When using both adapter harnesses, don't forget to connect the two blue wires together. I used a small wire nut for that.
