Fantastic that you got your Rotus running! Congratulations!
My wiring is a custom loom made 18 years ago by a tech who used to work for Custer at Rotus. The old loom was so bad that the only thing to do was start over. There is no schematic but rather standard colors for functions. I suggest that you use a multimeter to check continuity between two points and document as needed. Also know each fuse connects to what function, etc.
