The solenoid should not have a polarity, but some have one side grounded to the case so you should use the yellow/green for ground and yellow/red for power. Ignition/stater switches can be wired with a common ground ground that connects when the key is turned or a common power lead that connects to the associated contacts. If your switch uses a common power lead, ground the yellow/green solenoid wire and run the yellow/red to the starter pole of the switch. If your switch uses a common ground, run the yellow/red to the battery and the yellow/green to the starter pole of the switch.
