Main Relay: Notes
The main relay is located in the relay holder under the dashboard near the steering wheel.
When the ignition is in position "ON", +15 will be supplied to control module pin 43. The control module will then ground pin 26 to activate the main relay. From main relay pin 87, the control module will simultaneously receive supply voltage on pin 1. The control module supply is used internally to supply the throttle motor.
When the ignition switch is turned to "OFF", the main relay remains operated for a further 10 seconds to allow adaptation of the throttle valve's fully closed position.
