Need panel wiring info

[wincrasher]

This is the back of my distribution panel.

What I think I'm looking at is the yellow wires on the left are positive 12v and the white wires in the block on the right is negative 12v. There are other sealed connections further right that I believe are the 110v connections.

I put a continuity meter on the ground on the converter, and touched the block with the white wires and it illuminated. So I'm fairly certain that is negative.

Correct?

I would use a volt meter to test positive or negative, not a continuity light. But I think you're right, anyways,

Yep. Ground is a bus. The yellow wires are going to individual fuses that feed the +12 to the various circuits. There should also be a large "+12VDC In" lug somewhere that feeds the +12 to a bus that feeds the fuses.

Thanks. I'm wanting to add a 12v/voltmeter/usb panel to the dinette seat.

Looks like I have an open slot, so I'm going to connect it there and add a 20amp fuse.

Looks like I got it. No fires yet.
