The Chrysler K-Car Club

Ok I'm assuming the Power Loss Light bulb is just burned out. Every other light on the dash cluster works even all the illumination lights. But some reason the Power Loss Light doesn't light up anymore when you crank the engine or check for codes. I've taken the trim panels off so far because I had to remove the radio to be repaired. I have yet to remove the gauge cluster because I don't want to further mess anything up until I know what I'm facing. I've done gauge bulb replacements on my 65 Plymouth Valiant, 73 Dodge Charger, 93 Ford Ranger, and 98 Ford Ranger. The 73 Charger actually being the most work. I've got two boxes 10 count of 194 bulbs so I'm going to replace all the bulbs while I've got the cluster out. I'm just wondering is it going to be a struggle to get behind the cluster engouh to unplug the bulkhead connector and speedometer cable?
