I'm not sure if that motor is reversible but in this application it is not. I believe it has brushes - the one I used to own smelled like an old drill motor. There is a large resistor and switches used to slow the speed just as the tonearm starts to lower. Be sure these switches are operating correctly or you will ruin needles and record edges quickly as it slams down.

I have a Mills Do Re Mi that is without a selection (carousel) drive motor. I have acquired one but need help wiring it in. The motor has four wires (two of course for the AC). Any diagram or drawing directing me where each of these go would be appreciated.
Service manuals are available here: https://victoryglass.com/product/part-number-71-1264/
Generally speaking, AC motors with four wires are often reversible. Power is applied to two wires. A capacitor is switched in to the other pair of wires to change directions. Seeburg used this setup for decades.
I have no idea about the Mills specifically, but when you get the manual it should help.
