Power Amplifier
The head unit (C0092) is connected to the power amplifier (C0491) as follows:

A positive signal is provided by the head unit to the power amplifier on a BG wire. This 
signal is used by the power amplifier for the RH rear speakers.

A negative signal is provided by the head unit to the power amplifier on a BO wire. This 
signal is used by the power amplifier for the RH rear speakers.

A positive signal is provided by the head unit to the...

DESCRIPTION AND OPERATION
FREELANDER 02MY 4.151
The power amplifier (C0491) receives inputs from the head unit (C0092) and relays them to 
the speakers as follows:
NOTE: The LH and RH speakers share the same connector numbers as they utilise the 
same door harness.

A positive signal is provided by the power amplifier to the RH front mid-range speaker 
(C0369) on an OK wire. The RH front mid-range speaker (C0369) is provided a 
negative signal by the power amplifier (C0491) on an OB wire.

A positive...

Remote Audio Controls
The remote control interface unit (C1897) provides a feed via the rotary coupler (C0082) to 
the remote audio controls (C1254) on a BR wire. The remote audio controls contain a 
number of normally open switches and resistors. When either of the controls are moved, one 
of the switches closes and a voltage is returned to the interface unit (C1897) on a BW wire. 
The value of the voltage returned to the interface unit is dependent upon...

FUEL PUMP
DESCRIPTION
Td4
The fuel system on Td4 vehicles features two fuel pumps. A low pressure fuel pump is 
mounted in the plastic fuel tank, and delivers Diesel fuel to the high pressure Fuel Injection 
Pump (FIP). The system also incorporates a spill return line, which returns any unused 
Diesel fuel back to the tank. For more information on the Td4 fuel system, refer to the  Fuel 
Delivery System – Td4  section of the System Description and Operation...

Inertia Switch
Fuse 10 of the engine compartment fuse box (C0575) provides a constant battery feed to 
the inertia switch (C0123) on a G wire. The inertia switch is a normally closed switch. If the 
inertia switch hasnt been tripped, current flows across the switch (C0123) to the fuel pump 
relay coil (C0730) on a GU wire.
The inertia switch (C0123) also provides a feed to the Central Control Unit (CCU) (C0428) 
on a GU wire. For more information on the...
