Need help locating 67 dash horn wire

[THS70]

Hi guys I'm new to the forum. I have my sons 67 Mustang that we've been working on the last few years. We're at the finish line but I can't figure out what wires under the dash are for the horn button. I have a new steering column wire harness installed but not sure which horn wire goes to it. The horn never worked before and the wires under the dash were a mess. Any help appreciated.
Thanks, Anthony

While this is a wiring diagram for a 68, I suspect the steering column wiring is the same. Verify that before trusting this. You should be able to trace and find the wiring you need to connect the horn. Good luck.
