Chester,

You got it !!!!!

Wire it like you drew it.

Remember to reverse red and black on the second AC unit contactors. That way, you keep the power balanced on the legs as much as possible.

Don't let Bill's pictures fool you.

You could also take the neutral that will be in your junction box and connect that to one side of the triggers. You save running two wires that way. But's it's more fool proof for you to wire it the way you drew it.
