Custom Cruiser RWD V8-350 5.7L (1992)
Brake Warning Indicator: Description and Operation
Voltage is applied to the "BRAKE" Indicator from Fuse 17 when the Ignition Switch is turned to "RUN", "BULB TEST" or "START". The
"BRAKE" Indicator is controlled by any one of three switches: the Brake Pressure Switch, Ignition Switch or Park Brake Switch.
When the Ignition Switch is turned to "BULB TEST" or "START", CKT 33 is grounded through the Ignition Switch to activate the "BRAKE"
Indicator. When the Brake Pressure Switch is closed, CKT 33 is grounded through the contacts of the Brake Pressure Switch to activate the "BRAKE"
Indicator. On vehicles not equipped with Daytime Running Lights, CKT 1492 is grounded through the Park Brake Switch when the Park Brake is set, to
activate the "BRAKE" Indicator.
On vehicles equipped with Daytime Running Lights, CKT 1492 to the Daytime Running Lights (DRL) Module is grounded with the Park Brake
Switch set. With the Daytime Running Lights Module grounded through CKT 1492, the module provides ground to CKT 33, lighting the "BRAKE"
Indicator.
