'66 Heater/AC wiring questions

[Rust-O-Matic]

Ah-ha! Thanks fot the info, I totally overlooked the "A.C. & Heater" fuse on the fuse block. The wiring diagram doesn't appear to show it that way so I kinda ignored it. That makes sense though. Any idea why there's two power wires running to the system?

Also still looking for a pic of the wire running from the horn relay if anybody has one. Just curious if it runs along the side of the main front harness or what, and where it goes through the firewall.

Not enough wire (size) in the main harness to support blower and all of the controls/relays and the compressor so they split the comp off with its own feed (not through the ignition switch also) would my guess

I looked around for pics but did not find any closeups that showed what you need
