I also finally got around to putting my Autometer Monster Tach in. Electrical wiring is my worst nightmare, and I know almost nothing about it. But somehow I still managed to do it. I'm looking into one of the wiring harness kits offered by Painless Wiring, but I don't know if I could handle that. Or if its even worth it right now.
So I picked the lunar series tach, because of its greenish glow at night. Autometer just recently released their NV gauges, which are actually green, and of course I want those now. I would like to upgrade my dash cluster to all NV gauges, but it looked a little difficult. I did purchase 3 2-1/16th gauges for my A-pillar though. That will be the next project.

I wasn't quite sure what the hell I was looking at here, but somehow I got it working. Sweet!
