Default 1968 Olds Turn Signal Wiring - For my Street Rod

I have a 1968 Olds Cutlass column in my 46 Chevy Street rod and am using an aftermarket harness.

I am chasing the connections for the turn signals and brake switch and am having terrible luck.

Does anyone know the colors and circuits for the 1968 GM Turnsignal switch? It seems that I can't find a spec of info on the web, other than everyone wanting to sell me a diagram.

I have shop manuals for 66 GM, 69 Pontiac, 69 Olds, 72 Olds, 65 Vette. It seems that the harness colors are different, and in 69 they went to a column ignition so I dont know if that makes a difference. Would the terminal sequence be the same regardless of wiring colors?

I am not the best at wiring but have the whole car done except for the turn signal switch.
