Need help with SR 40" Rigid install

[mriboy]

Didn't get any instructions with it and I don't want to fry something need help.
1. The switch for the light only had the black wire connected does the red or blue wire go in the middle connector? Thinking it goes black, blue than red.
2. What hole size do I need to drill for the switch?
3.Do the pos and neg on the end of the wiring go on the corresponding battery terminals or do I ground the neg to the frame?
4. There looks to be a connector black box with a metal ring attached to it do I ground that or is it just so u can screw it to somewhere to mount?

Thanks for the help in advance,
Mike

blue wire goes in the middle, so you are correct. red and black to the battery. And the black box gets bolted on, no ground needed.
