I'm not sure if the '02s are like my '98 under the dash, but I'll assume they are. If you remove the knee bolster under the steering column, there is a metal cross brace. The bottom screws of the bolster screw into it. I fastend my Painless fuse block to this cross brace over to the right. The fuse block sits more or less vertical with the fuses facing you when the bolster is removed. This turned out to be a pretty handy spot. I'd have to remove the bolster on mine to check the details as it's been a while since I was under there.
As for the other parts, I've fastened some to the steering column and I found a spot on the fire wall next to the steering column for another. Wire ties, velcro, or double-sided 3M trim tape all work well.
