found this page on the interwebs that explains what each wire does on the turn signal switch wiring harness ie the non ignition switch wires that run up the steering column

this isn't the exact part / plug match but the wires seem identical, so it might could help somebody out, I know it beats the wiring schematics for me anyways

white - stop lamp switch (what is that?)

green - right rear turn signal
yellow - left rear turn signal

purple - turn flasher (what is that?)

brown - hazard flasher

dark blue - right front turn signal
light blue - left front turn signal

black - horn
