How the 58 to 9/71 turn switch works electrically
9/71 to 9/72 Turn Signal Switch
Everything is the same internally/externally as the 58 to 9/71 turn signal switch, but this switch has a 6 pin male connector instead of 6 bullet connectors
9/72 to 9/77 Turn Signal Switch
This is the year the column changed to having the dimmer on the column and the turn switch built into the colum instead of external to the column. The 9/72 to 9/77 column has three connectors, 1 6 pin (Turn Signal and Horn), 1 Green 4 pin (Key Switch), and 1 White 4 pin (Dimmer Switch)
