Tach and Dwell Meter

[Valero]

Any help on hooking up the 2 wires of a Tach/Dwell meter to adjust/verify RPM ?

RPM's are based off of the pulses your ignition coil puts out(negative side). If you buy an aftermarket tach, and it doesn't have a 3cyl option, it won't give you the right RPM's.

That's cool, the question still stands: How or where do you hook up the Tach and dwell on a 94 metro. My tach goes down to 4 cyl but I can easily (Mathematically) convert it to 3.
thanks geozukigti

Hook the tach's signal wire up to the negative wire on the ignition coil. I would still recemmond buying a proper tach.

What is a "proper tach."
and where do you get one?
I want to install one in my tracker...

Ohh, your tracker should have a 4cyl engine in it. It'll work just fine then.
