Accessories/ Installation Procedure
with the ignition, connect the ignition wire to a power
source that can be turned on and off with the ignition key.
Use a commercially available conversion connector if the
connector does not fit in the vehicle connector.
Insulate unconnected wires with vinyl tape or other similar
material. To prevent a short circuit, do not remove the caps
on the ends of the unconnected wires or the terminals.
If the console has a lid, make sure to install the unit so that
the faceplate will not hit the lid when closing and opening.
If the fuse blows, first make sure the wires aren’t touching
to cause a short circuit, then replace the old fuse with one
with the same rating.
