The center pin of a 6-way does carry the 12 volt accessory circuit like you described. The brake controller output circuit would then be the pin in the 10:00 position like what you see in the diagram attached.

You should note that in some cases these two circuits are switched and are opposite of the diagram. Since this is a pretty common issue that frustrates people and you asked specifically about those two circuits on a 6-way I figured it was worth mentioning.
