[QUOTE="machoheadgames, post: 436304, member: 18789"] Not how that works. The 4wd light bulb is powered all the time with ignition power. the bulb's ground runs out to the front axle. When the vacuum CAD moves the fork over, the switch is closed and lets the bulb ground flow to the ground source and then the bulb lights up. If your light is actuating opposite of when it is supposed to, I would suspect your vacuum lines are flipped and operating the CAD fork opposite of when they're supposed to. Meaning your 4WD is not working when it's supposed to either. Verify if you even have the vacuum setup anymore. [/QUOTE]
