Wiring up an AC Motor?

I’ve come across a light-duty AC motor that I want to use in a garage door opener. Problem is, this is an old motor that doesn’t seem to have any wiring diagram.

Does anyone in the collective know how I would wire it up?

This is what the labels on the motor say:
The number on it is 5KCP29MG and 4047CT
115V 4.2A 1050 RPM CW/CCW 1/3HP 60Hz

There arejust four wires coming from it two yellows a black and a red. Armature is strictly non energized. It’s from/for an industrial garage door opener.
