coolant recovery question

[badform]

Okay... I think I'm missing something really obvious here, but I can't seem to find the answer, which means I'm probably not asking the right question.

In order to install a coolant recovery bottle in my truck, I know that I need to get a two way cap rated for ~14psi. The top of the bottle connects to the nipple just below the cap on the radiator. Where do I hook up the hose from the bottom of the bottle?

Does it go to the bottom of radiator side tank? Does it tee into the same line at the top? *confused*

Thanks!
