Saw a previous posting where a user was helped with a different model
than mine a couple of years ago.

I've got an Alliance U-110 Tenna Rotor and the schematics are missing
for the in house controller. Four terminals, labeled 1-4, no idea how
they connect with with the wires. I inherited a system already in use,
and the wires which are in place are red, green, black and white. Any
ideas about which goes to which terminal?

Sadly uneducated,

I used to install U-100's many years ago (a side job while in college)
and remember if you use the included strain relief at the motor end
with a four wire flat cable, the four wires became 1, 2, 4, and 3
because of the way the screw terminals were laid out on the motor.
You, therefore, had to swap the 3rd and 4th wires on the control box.
I always wondered why they did it that way. We had many repair calls
because an owner would disconnect the control box and then reconnect
it the obvious way... wrong. Perhaps they fixed that problem on the
U-110.
