I am installing an American Autowire kit into my 1971 Cutlass. I have attached the pictures. The connector in the kit is missing 2 wires (first pic). On the original connector (second Pic), what are the "E" and "F". I believe the "E" is the ground from the driver side door jam switch. Where does "F" go to? I think it is the horn relay. If so, which connector on the horn relay? The third picture is the wiring breakdown from American Autowire.

My print shows two wires going to key buzzer switch.


My print shows two wires going to buzzer for the ignition switch

 

And this is why I dislike aftermarket wire harnesses...
Since you apparently have the 1971 CSM, the pinouts for the turn signal connector are in the lower RH corner of the wiring diagram. Specifically, the black and pink/black are the wires that go to the key buzzer switch.
