If your not sideways and all jacked up you must be playing following the leader...

white = illumination
black = ground
red = switched power
green = tach input

So white and red can basically go together, and thanks

If it's a memory tach and you hook the red to the switched power when you cut the switch off it will not hold the memory. You can hook up the red to a solid power source like the hot side of the solenoid and the white to the switch for the lights.

An Auto Meter tach should hold it's memory even with switch power shut off, we can recheck ours hours after the race and it's still saved.
