The radio system includes two separate wires, one orange (66") and one
green (106"). The HLH4952A Fuse Kit contains crimp-on ring tongue lugs
and crimp-on spade lugs. The spade lugs allow connection to hot leads at
the fuse block of the vehicle, and the ring tongue lugs permit attachment
to screw terminals. Determine from Table 1 which radio functions are to be
switched through the vehicle ignition switch.
A typical system allows the receiver to operate with the radio switched on
while the ignition switch is in the off position, but the transmitter will not
operate unless the ignition switch is in the on position. In this case, connect
the orange wire to the accessory terminal of the ignition switch and the
green wire to the ungrounded terminal of the battery or starter solenoid.
!
DO NOT connect either lead to the ungrounded terminal of
the battery at this time.
