What accessory plug does the roadlamp harness plug into?What color plug?There is yellow,orange,and red.
I've found these to be pretty helpful.

Check out my Reply #5. Looks like it's the red one, as shown in the second schematic.

It looks like the green goes to the red plug and the pink wire off the relay goes to the yellow plug.Could confirm that.Thanks
It's too cold (19*F) in the garage today for me to crawl under the dash but these new pictures might help.
Thank you
It's always bugged me that there never was an accurate 1970 road lamp wiring schematic or connection diagram so I went under my dash. Thanks for motivating me. This is how my 1970 is and my road lamps work flawlessly.
(Edit) - Whether this is accurate or not I can't say for sure, namely because of that BROWN/TAN fed accessory plug. My actual plug is black (as seen in the picture), the only reference I could find is that '71 schematic showing the yellow plug being fed by a TAN wire.
