Turn off circuit breaker, unscrew ~4 screws on the cover of the compressor unit, take a picture of how old one is connected, unplug it, connect new one matching up the symbols or letters, confirm with the picture you took, screw the cover back on, and switch the circuit breaker back on.
Watch any of the available 5,000 YouTube videos if unsure.
