windshield wiper motor

OLD THREAD BUMP!!!

I am using the same switch and wipers, and had a question about wiring it if you dont mind. My plan was to bring power in to the switch, then H straight to the motor for H, L through a ballast to motor for L, but I am unsure how to wire the Park function, as my switch has only 1 port, and the motor has 2... does 1 power go to park?
