Remote Audio Controls
The remote 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 which way...

Fuel Pump Relay
The fuel pump relay coil receives a feed from the energised main relay. The earth path for 
the relay coil (C0575) is controlled by the ECM (C0913 on K Series vehicles, C0331 on KV6 
NAS vehicles, C0371 on KV6 vehicles) on a BP wire. The ECM will energise the fuel pump 
relay when it receives an ignition feed from fuse 6 of the passenger compartment fuse box 
(C0581) on a W wire.
The energised fuel pump relay (C0572) provides a feed to the...

Reverse Lamp Switch – Manual Transmission Only
Fuse 2 of the passenger compartment fuse box (C0581) provides an ignition feed to the 
reverse lamp switch (C0163) on a G wire. When reverse gear is selected, current flows 
across the switch (C0163 on Td4 vehicles, C0166 on K1.8 vehicles) to the PDC ECU 
(C0958) on a GN wire.
Reverse Lamp Relay – Automatic Transmission Only
The Electronic Automatic Transmission (EAT) ECU (C0932) monitors the condition of the...
