The harness you have pictured is the Toyota factory brake controller harness. Toyota usually issues these with each truck. This will work with the Prodigy P3 Brake Controller, # 90195, that you purchased.

The P3 should have come with a universal harness with 4 wires, blue, black, red and white. These wires will connect to the wires on your Toyota harness as follows.

Toyota Harness Black/Red to P3 Harness Black
Toyota Harness Green/White to P3 Harness Red
Toyota Harness Brown to P3 Harness White
Toyota Harness Red to P3 Harness Blue

The white plug on your Toyota harness will connect to the factory brake controller port under the dash on the left hand side of the emergency brake pedal. I have attached a video that shows where to locate this port for you to check out.
