Configuration II
If the assignment of pin 7 of the ISO plug is connected to the ignition, and pin 4 is connected to the
DC power supply, the connection of the cables should look like the connection presented on the dra-
wing below.
In the operating manual of the radio device, you can find the pin assignment for the “mute” signal. This
signal can occur on one of three cables marked with “mute1”, “mute2”, or “mute3”.
Connect the yellow “mute” cable to the switchbox using the correct cable from the car radio: “mute 1”,
“mute 2” or “mute3”.
ATTENTION:
The positive wires and ignition wires are protected in the casing of the switchbox with X
3A fuses.
