AMP Plugs used in spas over the last 20 years or so can be a bit confusing to wire up. Both the male, and the female plugs have a locating groove to show orientation, as well as the flat faces of 2 of the pins. Use the images below to ensure correct wring for pumps, blowers, heaters and other accessories.
Note that when fitting new leads to a 2-speed pump, that they use Black & Brown wires for the Active side of the wiring. Each manufacturer has used variations, where sometimes the Black is High-Speed, and sometimes the Brown is High-Speed, and Vice Versa. If the diagram in the pump is not there, these two wires can be swapped in the case where the High & Low speeds are incorrect.
