Be careful with elec schematics, there are some "out there" that are NOT factory but appear to be. Make sure you have the 67 Barracuda FSM supplement. It is the only factory schematic I found.
I have it in pdf and can email to you.
Theres only a couple suppliers of OEM style harness. For me to get a repop dash harness up in Canada, landed would be approx $1000. So I decided I could redo a harness I had. Tedious, but not $1000 lol
Good luck.
