If the car stereo features a mute jack, connect the yellow wire
of the mute cable to one of the «Mute in» jacks (1, 2 or 3).
Refer to your car stereo's manual to determine the position of
the mute jack.
CAUTION
- The red wire of the power cable must be
connected to the constant 12V supply, the orange
wire to the ignition 12V and the black wire to earth.
- Check the wiring diagram of the car stereo's ISO
power connector plug.
- On some vehicles, the positions of the red and
orange wires may need to be reversed.
This can easily be done by reversing the fuse
holders.
- Do not connect the orange wire to the constant
12V supply, as you could run down the vehicle's
battery.

You can use a specific adapter for the vehicle (not supplied)
If you do not have an adapter, connect each wire in turn if your
vehicle does not have ISO connector plugs.
