DESCRIPTION AND OPERATION 86-6-19

CD Switch Box

1 Noise filter
2 Connector C04
3 Internal switches

4 CD switch unit
5 Connector C07

The CD switch box is located below the steering column, on the passenger compartment fusebox bracket, behind the 
fascia closing panel. The box is secured to the bracket with two metal clips.

The switch box is connected to the lower DVD harness assembly. Two plugs from this harness connect into the switch 
box on opposite sides. A fly lead from one of the connectors provides for the connection of the integral noise filter.

Some CD switch boxes have two internal switches which are located next to one of the clips. This type of CD switch 
box can be used on vehicles with either a Becker head unit or an Alpine head unit. The switches have two positions; 
'Differential Audio' or 'Non-Differential Audio' which is defined by a decal above the switch aperture. For a Becker head 
unit the switches must be in the 'Non-Differential Audio' position, for an Alpine head unit the switches must be in the 
'Differential Audio' position.

CD switch boxes without the internal switches can only be used on vehicles with an Alpine head unit and cannot be 
used on vehicles with a Becker head unit.
