I never really looked at this untill today, and just figured i would do it like last year, but then i remembered last year had the db-15 connections with the ground in the top right corner. BUt this year with PWM type Dig I/O's each one has its own ground, so i was confused what to wire where.

Connect one side of each switch to signal and the other to ground. You really only require one ground connection and several signal connections.
