Wiring ballast and switch

[USMC Vet]

I have the original ballast with 3 wires,white,black and blue. Could someone explain where these wires go ? Also for the switch. How many wires tie into the power cord ?

So if I am interpreting this schematic correctly the black wire off the ballast and the black wire off the switch goes to the line power ?

[johnieG]

the black wire for the ballast goes to line neutral
the black wire for the switch goes to line hot
