Run power wire from battery through firewall
I did this after the fact, but as you can see I was able to run 2 4 guage wires with no problem. I don't think 2 0 guage wires would be any different.

Remove the one fastener that holds down the 'engine area trim piece'. This will allow you some room when cutting and running the wires through the gromet in the next step.

The picture doesn't show it too well, but on the other side of the fuse block, there is a big wiring harness that runs through a black rubber gromet. I used a sharp utility knife to cut an 'x' below the wire harness. Make sure you don't hit the harness by accident. Lift up on that trim piece if you need to. I was able to fit a flash light on top of the battery - let me see what I was doing and allowed me two free hands to do work instead of one holding up on the plastic.

Now, push your wire through the hole you made from the engine side. Putting yourself in a strange contorted position, you will be able to see the wire on the other side (in side the car). Pull the wire through.

Now lift up the carpet and run the wire along the door sill and up the door pillar. On the door pillar (with the plastic cover peice removed) you will see holes where you can pass the wire through to the glove box area. Put it back together in reverse order.

Just want to add a pic of what I did. The same way, but shows what gromet your talking about. Tie wrap the fuse holder to the cable and connected the 4awg to the battery post. Oh, its easier if you remove the 'engine area trim piece'. Just pop the second pin out near the top. Pull up the rubber seal and slide the whole thing out. This'll give you plenty of room to work with.

Heres one with the plastic back on and safety cap. Had to cut a slit in the cap so that it'll close flush with the new lug. The cable is pretty much hidden, I could wrap some more wire loom on it to make it look totally stock.

Thanks for the pics guys. I am going to install a laptop in the car. For now, I just need power for the laptop and the screen. I have a cigarette lighter adapter for the laptop from Lind, its very nice. The screen comes with an AC to DC plug/adapter (Xenarc) so I need a new adapter to run straight DC. With the battery lines run from above, what do you recomend I put on the other end? Could I just create 4 cigarette adapters here? That seems to be the more common way to run things or get adapters for.
Would this be a lot better than simply using the existing lighter adapter, and splitting that with a 2,3, or 4 plug splitters?
Links to supplies would be nice too.
Thanks,
Mark

Did you run the power cables in the cable tray on the passenger side? Since it was empty I used it.
There are two of them, a straight one and an angled one near the back.
The straight on was easy to run (ran a 4awg and a pair of 12awg speaker cables) The 2 cables (same size) fits pretty nice, any more or thicker would cause a problem.
The angle one is hard to run thru, had to pop the whole thing out to run the cables thru.
But man it is nice when it is done. I wanted to do the same on the driver side for the speaker cable, but that tray was filled already.

Yeah, I used the tray to run the wires on the passenger side. Like you said, easy. As for speaker wires, I ran them up the center console, to the left of the parking brake and shifter. May want to check that out.

Since my current plan is only to power a PC, is there a good reason why I should run a power wire from the battery, as oppossed to just picking up a 12v position from the fuse box under the dash? Since I also need to run a wire from my ACC to the computer, I was thinking that maybe the easiest thing to do is just pick up both these points from the fuse box. Does this make sense?

anyway you can show how/where to connect the remote lead wire to the fuse box or where ever you connect it. i've always gotten confused about that part. but these pics of the battery wire helped too. i want to get my box in but have been too lazy. but i need to get to it soon cause it's just sittin in my room doing nothing.
thanks
