Im replacing a gauge cluster in my 85 c10. the truck had a voltmeter but was not hooked up. grounding location is not a problem, the 12v switch power is my problem. the truck is a wire mess from previous owner. there is not a radio in the truck and the cig lighter is constant hot. not exactly sure if the cig lighter should be constant hot either... any suggestion for a 12v switch source?

Thanks
Jeff
