Questions about Downboy 750 converter board. Any pictures?

[KDOG3]

I'd like to see a close up picture of the DB750 if possible. I need to know where the leads go. I ordered one, but it will be a while before I see it. Does it have the negative contact "ring" around the outside edge? The positive contact area on the back center? The pic on the shoppes' website isn't great. Thanks for any help.

If I remember, there is a ring but it is not connected!

Ok, so I would have to run a wire from ground point to the housing of the LED module right?
