I've tried almost everything my prndl light stays on and battery goes dead I have replaced the alternator battery ecm key cylinder brake light switch dash cluster alternator wiring added new ground wires and about lost my mind

 

I have the same exact issue, cluster rebuild scheduled for tomorrow have you figured it out yet? I have replaced batt alternator and check ignition switch and cylinder?

 

I put a new cluster in mine and it didn't fix It I'm looking at it possibly being the actual ignition switch
