the power fuse to open, and it will have to be replaced.
■ Maximum input voltage is 16.0 volts.

Notes on cable routing
■ If possible, use existing slots and channels in the vehicle for connection.
■ Route the cables so that they will not tangle or interfere with the
movement of seats, pedals, and emergency brakes.
■ Avoid routing cables under floor mats in foot traffic areas so they will
not catch on your feet.
■ Route the cables so that they will not cause electrical interference.
■ Be sure to cut the car interface cable to the necessary length, and then
install the fuse holders where they are easily accessible. See
Connection diagram, page 20.
■ Be sure that the connector between GCK-10 and GCK-11 is inside the
vehicle. See figure below.
