Dash and turn signal issues

heres some more photos.

After cleaning up the column harness, the only left over wire was a pink one from the column? posted a photo, didnt know if it was okay to be left out, or where it goes to, im thinking it might be a 73 thing.

The wires on the solenoid thing has 2 pink and 1 red? emergency flasher? why 2 pink?
