Found the text file that has the info for you. Web links that still work! Your WH5 ballast(s) is(are) able to run either 1, 2 or 3 F39 T5HO tubes. Use wiring diagrams 14, 9 or 8 respectively. Top of page 31 in the pdf of following link:

Link to another site with wiring diagrams. Looks like you already have them, but here it is. Perhaps others will benefit.

With respect to a starting aid, I recall noting that as well, but they don't give much more info on that aspect. The lamps worked fine without a starting aid but I did add an extra ground wire to each clip on reflector. I think the ground wires also help minimize induced voltage & minor zaps when you touch them & the water at the same time! Also had water proof end caps. I mounted fans over the ends of the tubes for cooling since I was over driving them with the Workhorse 8 ballasts. I'll probably never use the parts again, so if you need some good end caps, I'd be willing to fire them off to Saskatoon in the mail.
Ensure you use the jumper wires from pin to pin on the end caps.
