You don't mention the specific brand of meter...most of the time you can look up the installation sheet/manual online, which I HIGHLY recommend when dealing with ignition components.

But in general, the four wires are typically as follows:

Green: goes to the negative side of the ignition coil or the tach output terminal of your OBD-I port.

Red: switched and fused 12-V power

Yellow: 12-V power from the instrument panel lighting (controls the meter's backlight)

Black: ground wire

There is probably also some switches under the back cover of the meter to change it to read 4-, 6-, or 8-cylinder engines. You may have to guess and check on this, but for DIP-style switches, 4-cylinder is usually both switches either ON or OFF.

Hope this helps!

I was close. Here's a install sheet for one of their gauges:

Find your specific model and compare features. Good luck!
