I believe the vast majority of the 'dash lighting up' issues stems from the harness connector mounted just above the parking break. It has caused me issues from the 'dash lighting up' with multiple displays exactly like the OP describes (revolving "Starting System Failure", "Advance Trak Failure" "Low Oil Pressure", "High Engine Temperature", the "Wrench" - it even set codes that the dealer service manager told me do not exist in their manuals), to rear view camera not working or being intermittent. It is a very real problem. Now if anything happens to my truck, I START with that connector (which at least two data networks flow through, including the CAN - big time data transfers).
Please don't anyone be offended - I know other issues can cause these symptoms, but I just start with that connector due to my experiences.
