Underhood Lamp: Description and Operation
Voltage for the underhood lamp is supplied by the RED (2) wire from the battery junction block through the in-line fuse and ORN (40) wire. The
underhood lamp is grounded through the BLK (150) wire. When the hood is raised, a mercury switch within the lamp assembly closes, completing the
ground path; this allows the lamp to light.
