Most tachs have a green wire that goes to the negative side of the coil, and at least two more wires for hot and ground. Sometimes there are two hots. One for the tach and one for the light. Check inside your tach to determine which wire goes to ground, and you should be able to figure it out from there.

Why does your 1992 Toyota Previa driver's side mirror have 4 wires when all replacement mirrors have 3 It is NOT a heated mirror.?
I just changed one. Their are four wires where the wires come into the mirror but only three at the plug that does into the wire harness in the door.

The plug has both grounds combined into one wire.
