A vehicle power outlet switch can include a threshold detector for comparing a predetermined threshold with a vehicle battery characteristic and a power switch controlled by the output of the threshold detector. The display enclosure includes at least one WAN antenna configured to rotate about an axis such that when closed the antenna forms part of the display enclosure, and when rotated to an open position the antenna extends above the display enclosure. The fuel metering system of the present invention has the capability of independently controlling fuel flow during transitions in engine operation or allowing fuel to flow simultaneously through all manifolds to prevent blowout, optimizing combustion temperature distributions, or minimizing combustion emissions.
