Is the connector installed the correct direction? That could explain some of the wire positions.
This is the view looking at the firewall from the engine compartment.

I don't think I've found any errors in the engine compartment diagram.
The only ones that are confusing are the tach wire (absent if car didn't come with tach); and the wiper motor wires which vary with the three different motors that came on those cars.
On the interior, the reverse light wire is blue instead of violet.
And I think there is one wire marked with two different colors, but that might have been a different year.
Big change from 67 to 68 was relocating the battery feed from Z to J.
Also the headlight wire colors were changed. Violet replaced black.
