I recently swapped my pre 98 decklid back to a post 98 decklid and i noticed my trunk light is not working. The bulb is good i followed the wires all the way back to the drivers side rear door. What causes the light to come on in the trunk? The 99svt has a spot for a switch to mount right behind the driver side hinge. my very early build 98 se has no spot for a switch but the trunk light always worked in it. Any one know what triggers the trunk light to come on?
