Thinking about buying one of those little sleek looking dual pod gauge clusters you install on your left-hand role-cage dealio, and I want one of the two gauges to be a Tach. Small, out of the way, but since my 97 civic doesn't have a tach, I would like to throw one on, so I can see just how far I am revving, and etc.

I have never installed one before, so i am not sure what to wire it to. Anyone tried this mod, and or have some info for a noob? I have some knowledge of electrical systems and am pretty good in finding stuff in the civic.

Thanks in advance!
