Wiring questions - Aux and/or 12v

Hi all,
I've got a quick question. I have a 98 12v which has a 7-way in the bed and a 7-way on the factory hitch. All the lights work great, as does the trailer brakes plug (#2). i have no power to the 12v pin (#4) or to the center aux pin.

I am going to be towing my friends travel camper which has 12v battery power for lots of the interior lights. does the trailer charge through the #2 pin, or should I have power to #4 or the center? looking at the wires going in I have the flat 4 plus a thick Black, blue, yellow, and white wire... White I guess is a heavier ground, and i dont know about the rest... just want to make sure we are good to go as its winter and we are heading to canada with the trailer. thanks
