Hi hanky, I guess my last reply didn't post. you were right, it was NOT the AC clutch, and it was not the other 11 codes, from )2 sensor all the way to crankcase sensors , etc... it was engine harness - found 4 wires that had rubbed each and peeled off and making contacts, re tapped each individually and truck runs as always - super. so the $$$ I was thinking and stressing about it - came to putting black tape !!!
Thanks for the support,
