Old plug was shorting out. Replaced with new plug and works flawlessly. Good price for a good product.

I replaced the original winding utility trailer jack on my 16 foot steel utility trailer with an electric 12 volt jack and I needed to use my accessory 7 contact plug to be combined with my original 4 wire receptical wire that had been previously used for rear trailer light signals. It was suggested that I combine the original 4 wire plug with the 7 wire contact plug instead of both plug.s. It was good advice. The single 7 wire plug for the rear signals and the electric jack are working very well together

It fit snuggly in the adapter on the truck, the cover fit snuggly on the 4 way terminals. I like the fact that the 3 female and 1 male prong which is the ground, fit snuggly with the 4 prong connector running the trailer lights.

Exactly as advertised. The flat trailer connector plugs in perfectly. So much easier to plug into my truck than the flat connector.
