I don't know how to put up a diagram on here but I have wired up a few of these. What I have always done is put the output wire from the ballast on one pin on the tube and neutral on the pin on the other end, then put the starter in a loop to the other two pins. Make sure the tube wattage is the same as the ballast and put the switch on the phase wire to the ballast. I always earth the ballast as well. Hope that makes sense.
