I forgot the 12 volts goes to the signal flasher and changes color again there before going to signal switch.
I was remembering a 72 harness when I said white went to bulkhead and changed colors before going to signal switch and skipped the flasher where it changed again. I was guessing the 68 is same.
At brake lamp switch 12 volts is pink in and white out to signal switch.
Steve, I don't have a printer, well I do have a old printer but no ink. I just can't do it on pc screen. My mind doesn't stay on track that good. On paper I can do side by side comparison, use highlighters, etc...
I'm sure you and Matt will finger it out.
