Here's the list of what my '63 has in it:
purple is (output) to the right rear T/S - brake light
pink is (output) to left rear T/S - brake light
dark blue is (output) to right front T/S
light blue is (output) to left front T/S
yellow is (input) from the T/S flasher in the fuseblock
green/brown is the (grounding) line from the horn relay to the contacts in the steering wheel. It changes colors at the connector plug, brown being the column side.
white is the (input) line from the brake light switch.
I've already put a later model GM column and switch into my truck, so if you need the color codes to match with, give a holler.
