Another radiator question:

There is a plugged outlet from the radiator on the passenger side near the top, under the top transmission cooler line.

I have read that there is a 'heater nipple' on some radiators, so i think that's what this is.

What should it go to? I have two cut hoses coming out of the firewall, which I believe are from the heater core. I'm just not sure what they should be plugged in to for my heater to work.
