The best way to "look" for power is to use a volt meter and test for it. That way you know when the power is available for your needs. Is it Battery power (available at all times directly from the battery), Ignition sourced (only available when the ignition is on) or System power (available when a particular system is energized). This way you don't have any surprises down the road with dead batty or your new system not functioning at all times you require it. Like previously stated, you can always tap off of the unused connectors. If you do not have heated seats, I would guess that the unused connectors would have provided a connection to the heated seat switches on the console. I hope this helps.
