Maestro, the plug you posted the link to has ONE terminal, hence the name single pole. This plug is designed for high amperage applications for the (+) connector where the device powered is grounded through the vehicle frame. There is no provision to run a ground through the body of this connector. What you want is the 2-pole connector shown at the bottom of that page.
Actually, not quite - look at the picture below.
It has two connection points - one for positive (center plug) and the exterior lug that bind to the body of the connector. This is for negative/ground, which means it expects connectivity through the socket body.
Now, the socket itself, I guess, is expected to be grounder through the frame - you're correct there.
My question was whether connecting to the socket _body_ via mounting bolts is sufficient conductivity.
