CAUTION: You must be very careful when connecting wires to the vehicle's electrical
system. Be sure you do not interface leads that are being used for factory
components in the vehicle (like an on-board computer). When making
connections at the fuse box, make sure there is an appropriate value fuse
on the circuit you plan to use. Failure to do so may result in damage to the
unit and/or the vehicle.
