    5 Door
    Fuse 14 of the passenger compartment fuse box (C0580) provides a constant battery feed 
    to the front interior lamp (C0355) on a P wire. When the interior lamp switch is in the normal 
    position, the earth path for the lamp (C0355) is controlled by the CCU (C0593) via the 
    passenger compartment fuse box (C0580) on a PW wire. The CCU will illuminate the interior 
    lamp if it senses any of the doors are open (see Central Control Unit – CCU).
    When the switch is pressed, current flows across the bulb (C0355) to earth on a B wire. This 
    results in the lamp being illuminated irrespective of the condition of the door switches.
    Fuse 14 (C0580) also provides a constant battery feed to the rear interior lamp (C0356) on 
    a P wire. When the interior lamp switch is in the normal position, the earth path for the lamp 
    (C0356) is controlled by the CCU (C0593) via the passenger compartment fuse box (C0580) 
    on a PW wire. The CCU will illuminate the interior lamp if it senses any of the doors are open 
    (see Central Control Unit – CCU).
    When the switch is pressed, current flows across the bulb (C0356) to earth on a B wire. This 
    results in the lamp being illuminated irrespective of the condition of the door switches.
    Map Reading Lamps (5 Door Vehicles Only)
    Fuse 14 of the passenger compartment fuse box (C0580) provides a constant battery feed 
    to both the LH and RH map reading lamp switches (C0355) on a P wire. When either of the 
    switches are pressed, current is able to flow across the switch to the map reading lamp bulb. 
    Both bulbs are earthed via the lamp fixings.
    Load Space Lamp
    Fuse 14 of the passenger compartment fuse box (C0583) provides a constant battery feed 
    to the load space lamp (C0119) on a P wire. The earth path for the load space lamp (C0120) 
    is controlled by the CCU (C0593) via the passenger compartment fuse box (C0580) on a 
    PW wire. The CCU will illuminate the interior lamp if it senses the tail door is open (see 
    Central Control Unit – CCU).
    Glove Box Lamp
    Fusible link 12 of the engine compartment fuse box (C0575) provides a constant battery feed 
    to the lighting switch (C0041) on an RN wire. When the lighting switch is turned to the side 
    or headlamp position, current flows across the switch to fuse 16 of the passenger 
    compartment fuse box (C0587) on an R wire. Fuse 16 (C0589) provides a feed to the glove 
    box lamp (C0227) on an RO wire.
    The earth path for the glove box lamp (C0235) is controlled by the glove box switch (C0238) 
    on a BR wire. When the glove box is opened, the switch closes and an earth path is created 
    via the passenger compartment fuse box (C0587) on a B wire.
