So much for being timely. I will type it out here instead:
91426 Diagnose radio staying on when key is removed. Inspect body harness connectors for corrosion no visible corrosion in connector b23 and b24 check voltage drop across terminal 3 and 15 on connector m16 there was a 1.5 voltage drop. Inspect body harness from dr frt to dr rear for short could not locate short. Went to remove termal 3 and 15 from connector found corrosion inside of connector. It was not visible from outside of the connector. Replaced dr side body harness under goodwill. Radio does not stay on now.
Like I said, I was lucky. The harness could have cost $800 and then the labour to replace it would have taken me up to a total around $1700. I think I will be buying Nissan from my dealer for a while to come.
