OPERATION
The ECCS Relay coil receives 12Volts DC from the battery through a fuse link. When the Ignition Switch is in the ON position, the coil of the
Main Relay is grounded through pin 4 of the ECM. With the relay coil grounded, the contact switch closes and supplies 12Volts DC to pin 38 of
the ECM.
