New_X_O,

I used the actual "snap down things" from Radio Shack ($1.99/pack). They eliminate the need for any cutting and are way too easy to use to consider any other method.

I really don't want to disassemble my dash for the 3rd time, but I'll try to explain everything here. When you have the gauges out, remember there are two wiring harnesses that plug into the gauge cluster? You will need to tap into the left side (brown connector). There will be a blue wire with a red stripe. This is the one you want to tap into. I found this by testing the voltage across the wire with the parking lights on and off (12V/0V respectively). I grounded the black wire to an existing screw that was within reach. You just loosen the screw a bit, create a hook shape on the end of the wire, loop it around the screw and tighten.

As far as the tape is concerened, lots of the area will be covered by the black piece that divides the gauges into 3 pods, so be as liberal as you can with the tape. If you have high spots, try bending them back a little by hand. This might help a little. I did that as well as making sure to pull out any slack as I was taping.

I hope this helps. I should have snapped some pictures when I was doing the job, sorry... I just wanted to get the damn thing together cause I was getting a little frustrated myself. Thinking back, it's easy now.
