2-pin male AMP plug

If you replace your hot tub control system with a newer model, it will probably use AMP plugs, and the old plugs on the pumps, blower, ozonator and light are not compatible. Luckily it is very easy to cut off the old plug and install a new one.

All new Balboa and Waterway control systems use AMP plugs.
