Hi guys, I recently picked up a 1994 CC Chevy. According the to PO, there was a pretty trick stereo system installed previously. By the time I got the truck, there was just the OE headunit and holes in all the doors and dash. I'd like to get the OE headunit working (power and signal) but I'm having trouble tracing the wires. I tried to pull the headunit but there is no connector behind it and the wiring runs under the dash to who knows where. Any thoughts or ideas on where to look for the wiring? TIA
