Do what now... 6-12 volt switch? usually if there is a switch it will be a selector switch to change from 4-6-8 cylinders, the voltage is somewhat moot as the tach gets its signal from the ignition coil. All the voltage does is supply current for the back light if it has one and the current power the movement. What we need to do is make sure the signal wire is connected to the correct side of the ignition coil.
