Connecting the ISO Connector (see p.12)
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.
Please be sure to reconnect the cable as shown 2 below to
install this unit to the Volkswagen vehicles.

is linked with the ignition, and the A-4 pin (yellow) is connected to

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.
