HELP!!! I need help to wire up my autometer tach, i see a black and white wire on top wich are ground and power right? This is where I'm lost, there is also another outlet of three wires that are red, green and black. Where do i connect these to??? Thanks in advance.

What kind of tach and didn't come w/ intructions? [&:]

Red=power
black=ground
white=usually for the light
green=neg side of coil

Like Pro said, The white is for the light so when you turn on your dash lights the tach's light comes on so be sure to find a source for that. The power is a key on source, not just running off the battery. I don't know about all tachs but the one I have from autometer has a couple of wires that are looped in the back. Those are for different size motors.....4 cyl,6 cyl..... if you have those there don't bother them. You don't have to do anything with those.

Did you buy it off of ebay or something?????

That's OK. It happens to all of us from time to time.

Does anyone know if a tach. adapter is available for early EE-4 ignitions, that just plugs on to coil and provides the negative wire to an aftermarket tach?? Thanks: AL
