Need some help!!!! (electrical)

[jsbihn]

Ok, here is my situation.
I have a 03 H2 and I am trying to get a few things wired in.
First situation is:
I am replacing one of my cigarette lighters/ 12V outlets in the front with a switch for my emergency flashers.

I have everything set and wired, test the leads and they are dead. No juice.
It is the 12V / cigarette lighter closest to the driver. So I am wondering if it is a bad fuse, but who knows. So I am looking for the fuse box and I can not find the inside electrical fuse box. the only fuse box I have seen is the one in the engine bay. If that is the only one, ok which fuse is the fuse I need to pull. Anyone have a pic or something that shows me where the fuse box is?

Second situation is:
I have finished installing an aftermarket amp to the stock Bose stereo. So I am troubled coming up with a good place to ground the amp and to also ground the PAC adapter. I am placing the amp under the rear drivers seat so I would like to have a grounding point close to there. As for the PAC adapter, it is in the dash so I would like to have a ground point in that area.

I appreciate any help you can come up with.
Thanks
