Well I am, Learning Electrical much better then Ever Before ! It seems easy for me when you have a Expert Guide Thanks Alan and others . My Hands on is much better then reading the Electrical Schematics from a manual not that would be impossible to perhaps someday surmount .
Yes ! My Own Take on the 1980 Yr Model is that in fact the Wiring itself is just fine with the exception of : The Printed Circuits ( Dash Pod Area ) is weak at the Hookup Points . The Connections from Relays to Wiring Connections ( Copper ) Corrosion /. then Rust .
( if your very careful you can avoid damage to the Printed circuit > Watch the hook up points )
I am in agreement with Alan the the Basic Panel Set up is indeed well done for Its time with room for expansion and the fact that "indeed the Panel is repairable when damaged " That's a Huge plus side
The Panel Needs Maintenance that's all 30 Min's a Year should do wonders .
A Tip on Relays You can many times remove 1 Relay to get to the Next Relay and so to the next one and so on . When one is removed it makes it more possible to insert a Pry Tool to Giggle the next relay Helping Its removal .
So Once My Compressor Wiring ( Now in order and Indeed working ) is behind me and the New Dryer in Hand with some R12 ( about 3 or 4 Cans )
I can try to change out all the Seals and inspect the Compressor Pulley for signs of oil from that seal IE " freon Leakage "
I can Move forward and try to find a AC Expert to Leak Test the system and do a a vacuum Test on it for about a hour or longer .
This chart seems to be about right
