How do trailer lights work?

I have been working on getting the trailer light connecter (truck side) hooked up and have gotten myself to a dead end.

I am trying to set up the truck to have a 4pin flat connecter. At the moment it has the square five pin block and a round 5pin farther at the rear of the cab.
What I cannot understand is how does a four wire connector (actually 3 because of the ground.) run the brake lights, left, right turnsignals and tail lights.
my best guess so far when tested produces a left turn signal, right turn signal looks like blinking brake lights , and tail lights that seem to be as bright as the brake lights. (I am using a test light, not the actual trailer lights..
any corrections will be greatly appreciated.
Thanks
jason
