It sounds like you have a version of a 5-Way flat wishbone harness like # A40W5B. A wishbone harness will have 2 running light wires attached to one running light pin.

White is ground, the two brown wires are for running lights, yellow is for left turn and brake lights, green is for right turn and brake lights, and blue is for a reverse electric lockout solenoid.

Since the wires on your trailer do not match up you would have to trace each wire back to determine the functions. Or you could attach 12 volt power to each wire in turn and see what turns on to determine function.
