If you are retro-fitting your spa or hot tub with a new control system (for example, our Balboa GS501), you may need to change the power cord plugs on your pump, blower, ozonator and other equipment to be compatible.

These AMP plug kits come with a 4-pin male connector and four pins. Different pieces of equipment will require different pin configurations, so check your wiring diagrams carefully. The female connections will be on the printed circuit board of the control system itself.
