wiring an Sierra ignition switch for 50 hp 4 stroke Yamaha

I am looking for the wiring color codes to wire in a new ignition switch. The new switch has 6 terminals. One for battery, one for ground, I guess these would be red and black wires, the other four are one for the magneto, one for the choke, one for the ignition and one for the solenoid. The motor is a 4 stroke 1999 T50TLRX. Does anyone know where I can find which colors go to which of these six terminals. Thank-you.
