So I picked up this 1966 Pontiac Star Chief that has been sitting since 1993 and I'm slowly giving the car to come around to be a fun family cruiser. The other night out of boredom I was playing with the radio and it was super quiet at that time and I heard just a faint sound coming from the dash and sure enough my factory radio does work. So I removed the dash pad tonight to switch out the speakers and to my surprise I found the factory original build sheet.

I was wanting to know if somebody could help explain what some of these different options are because I don't know the codes.
