NOTE
Daytime light control unit drives daytime running lights (DRL) at the front, plus tail/clearance/license/illumination lamps when the engine is running (alternator sense on pin 4). When the lighting switch is moved to 1ST/2ND the control unit transfers control to the conventional lighting circuit.
