I have an Essick 4700 CFM cooler, where the power cord was cut and had a custom 3-prong attached, to trim the cable length. I detached the prong when winterizing, not realizing that this cable doesn't use the standard white/black color-coding for hot/neutral (they're both wrapped in beige, though the ground wire is colored green underneath). How can I ensure I don't wire this backwards when re-connecting the 3-prong plug?
Inside the control box, the live wires appear to connect to "COM", and "A", and the latter appears to be part of the "FAN" grouping. (The "COM" also has a second wire protruding from the same port, which travels to the fan motor.)
