Hey, thanks! I did it last summer when I had some time off, so I thought it through and planned it carefully and it turned out nicely. Here's some more details....
I didn't want to cut my factory carpet to fit around the box, especially since the car has black interior. So I did it like this:
1) Got 4 round rubber feet from Lowe's and stuck them to the four corners of the bottom of the battery box, since there is a clump of wiring under where I mounted it that go to the gas tank. Putting the rubber feet under the box raised it up (about 1/2" to 3/4" I guess) where it doesn't touch the wiring and the box sits nice and firm and level.
2) Mounted the box through the floor with the threaded rods provided with the kit and hacked off the excess.
3) Drilled a hole behind the tag for the switch. I used the biggest drill bit I had, then hollowed out the rest with a grinding bit until the switch fit though. Then I mounted the switch.
4) Ran the red cable from the solonoid, through the rubber insulation that the steering colomn goes through, under the carpet, behind the inner-quarter-panel trim, to the switch's location (behind tag), cut the cable there and attached one side of the cable to one post on the switch and the other side to the other post, then ran the rest through the hole in the box and attached it to the + side of the battery.
5) Drilled a hole in the metal under where the switch is mounted, cleaned all the paint from around the hole, and mounted the ground wire using a bolt on top and a nut from under the car and tightened it down really good. Then attached the cable through the other hole in the box and attached it to the - side of the battery.
6) Drilled another small hole near the ground hole for the vent tube, attached the vent tube to the box and ran the tube down through the hole and cutt off the excess.
7) Then I just atached the box's lid and tightened it down with the washers and wing nuts and that part of the installation was done. Flipped the switch to "on" and cranked the car to see if everything worked....which it did.
8) For the rear carpet, like I said, I didn't want to hack up the factory carpet. So what I did was... took large sheets of paper and covered the hatch-floor area with them, taped them all together with masking tape, took a pencil and traced all around the perimeter of the hatch's edges and around the battery box. Then I removed the paper, cut the lines I had drawn with scissors. Then I took this "template" and put it on top of a sheet of peg-board I got at Lowe's (solid, without the little holes), and traced the pattern onto the board. then I cut it out with a jigsaw and covered it with black carpet (auto-store) with spray adhesive. For the backs of the rear seats I just measured the sizes of the original ones, traced it onto the remaining peg board, cut them out, and covered them with the black carpet also. Then I just attached them to the metal plates behind the seats.
It all fit great and even looked better then the factory stuff... and I didn't have to cut up any of my original stuff. The peg board is light and easy to cut and won't add any significant weight to the car. If you have no spare and jack, a heavier wood would be need, so it wouldn't cave in..... but I keep my spare/jack/wrench in the car because I'm paranoid. I just know that if I was to take it out, I would get a flat the next day!
Anyway... sorry this went on and on... but maybe it will be of some help to someone.
