Ati 80w ballast wiring help

[FarmerTy]

So, I got two of the ATI ballasts to run 3 80w bulbs. I wired the one ballast for two bulbs and it worked perfectly.

Now, I'm not sure how to wire the single bulb to the ballast.

Here's the diagram on the ballast. Could anybody with more experience point me in the right direction?

Nevermind, I figured it out. For future reference for anybody else, use 1-2 and 5-6.
