since this topic often arises - here is some general tach wiring info:

Most tachs are real easy to install. Several varieties from the ones that mount on your hood, to those that mount on your steering column or dashboard etc.

Generally there are 4 wires coming from it, white, black, red and green.

Just hook them up like this:

Black to ground.
Red to power source for tach.
White to power source for light in tach.
Green to tach. neg. side.

That ought to do it.
