Pass side is for the "Fan Switch". There should be a loose black wire somewhere around there. Ground that to the engine block and the fan will kick on.

That is the secondary (heavy duty) coolant fan switch if you have the dual coolant fans. If you have just the single coolant fan it is the coolant fan switch. No need to add primary to that since it would be the only switch for the fan.
