Questions about DC Controller

[CAMAROBOY69]

I tried contacting Jabin yesterday and today via e-mail with no luck. So I figured I would post in the next best place.
I have a few pics and want to verify any confusion so I hook this up correctly.
Questions
1. Is the little black think on the left the jumper?
2. Does that go vertical or horizontal across the pins? I assume vertical because it has 3 connections.
3. There is something attached to the lower left screw. Is the black thing the surge protector?
4. Does it look like I have the blue plug hooked up correctly on the 1,2 pins?
I am going in the garage within a couple hours to install this and want to make sure im in the right direction.
