Some circuits are triggered by the key in the "ACC" position (radio), others in the "ON" position, others only in the "START" position. The key cylinder has 'outputs' for each of those positions, which then triggers a number of relays, to power each of the circuits that need to be on at those times.
Get the diagrams for your truck and figure it out...
