Where do these wires go?

1975 F100 4wd 360 motor. I was under the dash the other day and found these 2 wires in a black conduit under the left side of dash. When I put a meter on them (no key in truck) the green with yellow strip wire is at 12v. The black with blue strip wire appears to be a ground or at least has no voltage on it. They both tie into a larger harness. If I check continuity between the black and blue wire and a ground point I can see about 4 ohms. Anyone have a clue what these might be for?? I also looked at an electrical schematic and can't find these colors anywhere other than green and yellow to ignition coil? Any help is appreciated

Those wires are for the dome light.
Here's a link to the page of the '75 wiring diagrams that shows the wiring:

Go to the 62D section (upper right hand corner of the diagram).

Thanks Mike - I had a different drawing. It makes sense since my door jamb switches are all broken. Someone must have pulled them apart electrically too. Cool - Appreciate the help!
