Yup, gotta little lite on the right side I think, I'd have to go look. Wiring diagram should show how wired, I am not sure. All I know is my old Fiat has a trunk light, and my wifes 02 Impreza does not. Drives her nuts.
Yep, that's for the trunk light. The trunk hinge hits it when the trunk is closed and causes the light to go out, but it is wired to the headlamps and license plate lights so it will not work with the lights off, just like the early model engine compartment lamps. Here's how it's wired:
black wire to ground
yellow/black wire to left headlamp
yellow/black wire to left license plate lamp
