CHEVROLET S-10 RADIO PROBLEM

2003 Chevrolet S-10 • 78,000 miles

Rebuilt motor on 2003 2.2l S10, new pcm programmed to Vin#, Radio does not work, courtesy lamps do not work. Getting a U1000, P1632, P1626 DTC codes, no secutity light coming on at all. Tried the relearn process, 10 min on 5 sec off etc.(But with no security light hard to tell). Truck did randomly start one time and stay running after I had disconnected the battery, pcm, and bcm then reconnected them, also the pedal position sensor was disconnected when it started. I have checked all grnds and still no luck. What circuit would disable the radio, courtesy lamps and some of the cluster lights? With the thing starting that one time I am inclined to beleive I have a shorted wire some where from removing the engine, but where?
