Main Position
With MAIN cruise control switch pushed in, current flows through terminal No. 6 (White wire) of the cruise control ECU, enters the cruise control switch through terminal No. 15 (White wire) and exits from cruise control switch terminal No. 17 (Brown wire) to ground. Current also flows from the gauges fuse through the cruise control indicator light to terminal No. 4 (Green/White wire) of the cruise control ECU. The MAIN position cruise control switch remains on and continues to supply current to the cruise control ECU.
