CRUISE CONTROL SYSTEM Cruise Control Switch Circuit

DESCRIPTION

This circuit sends a signal to the ECM depending on the cruise control main switch condition. The battery supplies positive (+) battery voltage to the circuit control main switch. Then terminal CCS of the ECM receives the voltage according to the switch condition.
