I purchased this from a local auto parts store as I needed it for a next day job, and paid several dollars more than it's listed for here. Overall, it's a good 4 pin wiring harness with a rugged molded-on connector body that appears more solid than on the wiring harness I replaced. I used this harness as part of a lighting upgrade project, replacing the existing stock lights on my 5'x8' utility trailer with LED lighting.
