Ok, first shot at posting so many pictures, but here goes.
First thing, you want to pull off the panels that will be in the way. This includes the one around the steering wheel, the one above the footwell and the one over the fuse box. The only one with a screw is the first one. On the bottom left of the steering wheel panel, there is the only screw. Any, this is what you'll be looking at, minus the wires you see.
Next, to find the spot where the wires come through. I couldn't get a good shot of it from the inside, it's a really tough spot! But this will give you an idea of where the wires come from.

See the yellow part there? That's some sort of insulation. The hole is right behind where that stuff lays down. To give you a better idea of where this is, here's a shot farther away. That's the clutch pedal on the right.
Here's the start of the wires. You can see both the (+) and (-) wires entering the fender here.
Start removing the splash shield, this will be easier with the steering wheel as far counter-clockwise as it goes.
Pull it back a little bit and look up inside. You can see my wires in this shot right here.
This is what the grommet looked like. These can be seen inside the drivers door, but they were the same as what was inside the fender. I would suggest putting a hole in the grommet and running your wires through that so they aren't rubbing against the metal hole, like mine are. Stupid mistake, I know. I'm ordering another grommet to fix this.
There you are, hope these help. Feel free to ask anything.
