Did you read the instructions?

Usually an aftermarket tach requires a + signal from the coil.

Usually goes like this:

Black wire= Ground
Red wire= Switched 12V source
Green wire= Coil
White wire= Instrument lights

It's really quite easy, the instructions will tell you everything, the hardest part is usually figuring out how to mount the tach where you want it.

Inline, you get better information if you give better information.
Year, model, trans, engine, options and mods for a start.
