The Purple to Yellow is Neutral-Safety or Clutch interlock starter interrupt wiring.

That flasher relay socket took some abuse. Probably the terminals got loose on the flasher relay and heated up from arcing between the male flasher terminal and the female harness terminal. Someone has gotten after the terminal in the melted socket with lord knows what in an abortive attempt to remove it. That socket is probably toast.
Dorman makes a two wire flasher socket with a pigtail. Look for Dorman 84734. You could solder and heatshrink the Dorman repair pigtail wires to your flasher wires and carefully screw a flasher relay mounting bracket to the now dead and empty flasher socket.
