Roadmaster V8-350 5.7L (1994)
Tail Lamp: Description and Operation
Voltage is applied at all times from I/P Fuse #31 to the Headlamp Switch and, if equipped, to the Auto Headlamp Control or DRL Module from CKT
240. With the Headlamp Switch in "PARK" or "HEAD" or with low light conditions if equipped with Twilight Sentinel, voltage is applied to CKT 9.
Current flows through CKT 9, to I/P Fuse Block which feeds all Park, Marker, Tail and License Lamps turning them "ON." The only lamps that see a
current from CKT 308 and do not turn "ON," are the turn filaments in the Park/Turn Lights. They do not turn "ON" because the voltage drop across the
Front Side Marker Lamps is much higher than that across the Turn Lamp Filaments.
