Connecting Cables to Terminals

Connecting the ISO Connector (see p.34)
The pin arrangement for the ISO connectors depends on the
type of vehicle you drive. Make sure to make the proper
connections to prevent damage to the unit.
The default connection for the wiring harness is described in 1
below. If the ISO connector pins are set as described in 2 or 3,
make the connection as illustrated.
1 (Default setting) The A-7 pin (red) of the vehicle's ISO connector
is linked with the ignition, and the A-4 pin (yellow) is connected to
the constant power supply.

the constant power supply, and the A-4 pin (yellow) is linked to
the ignition.

constant power supply (or both the A-7 (red) and A-4 (yellow) pins
are connected to the constant power supply).

NOTE
When the connection is made as in 3 above, the unit's power
will not be linked to the ignition key. For that reason, always
make sure to turn off the unit's power when the ignition is
turned off. To link the unit's power to the ignition, connect the
ignition cable (ACC...red) to a power source that can be turned
on and off with the ignition key.
