It may take a while but I'm sure you could get used to minor things like honking the horn with the signal switch, right turn with the hazard switch, left turn with the horn button, wait till you see what happens when you step on the brake peddle... Other than the gray wire the "new" one matches the wiring diagram in my 67 Service Manual. How do the colours match with the rest of the harness on the other side of the plug?
Black -horn Lt blue - left front turn signal Dk blue - right front turn signal Brown - emergency flasher Purple - blinker flasher (blinker supply) Yellow - left rear turn signal Dk green - right rear turn signal White - Stop light switch The wiring diagram shows "gray" going to instrument lighting.
