The inside terminals on the Pollak 6-Pole Round Pin Trailer Connector # PK11604 referenced in your question are labeled on the inside edge of the plastic with letters that identify their functions. The letters are as follows:

G - Ground
T - Running Lights
L - Left Turn
R - Right Turn
S- Brakes/12V Power
A - Brakes/ 12V Power

You will want to test the wires on your trailer for function to ensure you make the right connections. Strictly going by wire color isn't always the best method as trailer manufacturers or previous owners may have used different color wires than what is standard. I have attached a short installation video that you might also find helpful.
