Connecting Wires to Terminals

Connecting the ISO Connector (see p.24)
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.

connected to anything, while the A-7 pin (red) is connected to
the 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.
