Replaced factory cluster w aftermarket. Turn signal issues

And the hazard switch has 4 pins, that can actually hook up incorrectly and cause issues. Been there too.

**edit** ours was 67 so hazard switch was in bezel not in the column like yours would be.
Yes my flasher switch is a button in the column and is part of the turn signal switch wiring. The hazards seem to be functioning as normal.
