First off no flames on how this is gay or whatever. I don't want a monster tach, or a fucking AutoMeter speedo. I wanna see my speeds above 130mhp, and my new internals are made for 8k+ RPM, So I would like an OEM Honda solution.

I wanna put a GSR (or Si) guage cluster in my dash. Anyone know how this is done? Anyone with a detailed writeup?
