Installing a tach

to a 1996 2.2 liter cavalier if anyone could let me knows how to install a tach please let me know i would really appreciate it.
thanks

I have got the MSD Tach adapter and a tach for sale. I bought them for my old 2.2 and then bought my Honda.

The tach retails at like 40. The Adapter retails at 90. I still have the receipt for the adapter. Tach is out of package, but never used. It even has the little red lien set up for where the 2.2 redlines :) .

I will sell them both for 55 shipped.
