There is a factory-supplied customer access circuit that is HOT IN RUN and is fed off fuse CJB F29 (10A). White-blue wire, should be above the OBDII port and should be tagged.
If you need more than 10 amps, use that circuit to activate an added high-current relay.

Nope. The cigar lighter and the power points are all ALWAYS HOT on the '02 Super Duty.
