OK, the wire colors, not the plug color, determine application. However, If I had to guess, the 90° plug is probably the cigar lighter, the triple is accessory dash lights (radio, Rally Pac, etc) and the two singles accessory power (radio, etc). Not every wire was connected in every car.
Amateur restorer. Well, sometimes I have been paid for it. But not right now.
