'58 D100 dash/wiring question

First question I have is if you look at first picture, what do the 4 pull switches do? 3 are cable, and the 1 that looks like an H is wired. The second question is turn signal switch wiring..on the 2nd picture..there is light green&yellow and then dark green&yellow..trying to figure out witch is left turn signal and witch one is right turn signal...adding universal wiring harness. Any help would be greatly appreciated!
