I do not have an experience at American Autowire.
And likely you will not for your Galaxie either.
They do list a harness for mid 1960s Ford. However only has a drop down for Fairlane, Falcon, Mustang and Truck.
For kicks I clicked on Mustang. The result was .....

If the company does not make a harness for 65 Mustang, well the full sized ride owners were not even a thought.
The concept of a complete wiring harness made of quality material is great
The concept of a complete wiring harness made for the way the car is equipped is even better
All of that at a reasonable price would be a real winner.
Rarely does that exist in the classic automotive world on something other than a custom or one-off basis. And that would not align with the last point.
