Engine wire help 1972 V8 Manual

[9teen69]

Replaced my engine harness today, wires going to starter. When pulling out old harness I noticed these wires that were loose. Where do they go, what are they for? Photo taken with white towel are in question. Wires come from round hole in firewall. Just bought the truck a couple months ago. 350 w/manual, 72 Cheyenne

That plug looks like the one that plugs in at the A/C compressor.

The 2-wire harness goes to the AC compressor. The single wire that looks like it's orange should go to the blower motor. The other one looks like it might be a ground.

Weird. It doesn't have factory air, maybe just laying around all this time? The green wire with the heat protection and clamp was mounted alongside the wires going to starter. The "orange" wire is red.

Mine has the same thing but mine is a custom deluxe. I wanting to say I figured those must be for a/c as was said.
