[QUOTE="machoheadgames, post: 439989, member: 18789"] Gotcha. Probably is a printer circuit board issue then. The bulb does use a switched ground. The 5-gauge cluster has a switched ignition power circuit that powers the gauges (there might be 2 ignition power wires split amongst the 5 gauges, it’s been a while since I looked at the diagram) and they are each operated by ground so ground for the 4wd bulb runs through the CAD switch. Unfortunately you’ll probably need to either rig up your circuit board or buy another cluster, as I don’t think anyone sells a replacement circuit board for 92-95. But maybe that has changed since I last looked. [/QUOTE]
