Another oddity to add to my knowledge base...don't quite know if this was deliberate or a manufacturing error.
On all 1965 underdash harnesses (both early - 2 speed heater and late - 3 speed heater), there are four bullet connectors near the engine gauge feed firewall plug. These are: black/blue (courtesy lights), green/yellow(fused hot), blue/red (PRNDL lamp feed), and the interconnection bullets for the neutral safety switch (red/blue).
On an early version, I ran across a harness without the green/yellow wiring. The rest of the circuit is intact, and no wires were cut. Together with the black/blue and blue/red, these are the feeds for the console and PRNDL shifter lamp system. There's no other purpose for the black/blue plug other than the console that I am aware of, so I don't know why the green/yellow line was deleted.
This is the first example out of 27 refurbished 1965 harnesses I've done. I have probably cannibalized another 25 or so, but really don't pay attention to that detail when harvesting parts. I probably have another 25 or so I have yet to examine.
