Brake Lamp Description

The brake lamps are operated by a switch mounted on the pedal box. The switch, when operated, supplies power to two brake lights located in the tail lamp units and a high mounted brake light. All brake light bulbs are rated at 21 Watts. A feed is provided to the trailer pick-up (if fitted) when the brake switch is operated. When the brake light switch is in the open position feeds are routed through the switch contacts to give:

Automatic V8 vehicles: A feed to the cruise control ECU for cruise control operation.

Manual V8 vehicles: A feed to the clutch pedal switch for cruise control operation.

Td5 vehicles: A feed to the Engine Control Module (ECM) for cruise control operation.
