Tail Lamp: Description and Operation

Circuit Description
Battery voltage is applied at all times to both the coil and contact of the tail lamp relay from Fusible link BATT. With the light switch in PARK or HEAD, the coil of the tail lamp relay is grounded through the ETACM/TACM.

Battery voltage from fuse 6 and fuse 7 is then applied to the lamps (side marker lamps, tail lamps, park lamps and license lamps) through the closed tail lamp relay contact and all the lamps go on.
