‘65 Mustang - Need help identifying some wires

I have a ‘65 Mustang and recently ordered a new headlight wiring harness from CJ Pony parts (headlight-to-firewall-wiring-harness-made-for-gauges-1965 p/n WHL2B) while replacing the old harness, I found three connectors on the harness that had nowhere to connect to in the engine bay.

The first was a single solid gray wire with a male bullet end, it exited the new harness right by the firewall connector plug.

The next two exited the new harness right by the passenger side horn wires, the were a solid black and a solid gray wire and each had female connectors for bullet connectors.

I used the online help at CJ Pony parts, but after waiting 30 minutes the only thing the guy said was “I don’t know what they are, you’ll have to refer to a wiring diagram.

I had referred to a wiring diagram and found nothing like these wires. Except in cars with fog lights but there would be another gray wire and black wire by the driver side horn, which my harness doesn’t have.

Unless there is a separate fog light harness that connects into the gray and black wires on my passenger side and continues to both lights?

I have some pictures, but being new my post count isn’t high enough to attach them yet... sorry.

Any help identifying what these go to would be greatly appreciated.

Maryland (but not for long)

There are a few different engine/gauge cluster harnesses for those cars. I just rewired everything from the dash forward on my dad's 65'. I found a great source for the harnesses on eBay. They were very specific about the dash harness. I'll see if I can dig up some more information.

For everything that is worthwhile, there is a counterfeit.
