This cord is frequently used to connect a one-speed pump to your hot tub's control system. It has three wires to connect to the pump and a mini J&J plup with three pins which plugs into your hot tub's control system. This cable is most frequently used with Gecko control systems, or older Balboa control systems.
Two cable lengths are available, approximately 48" or 120 cm, and 96" or 240 cm.
To make sure you have the correct cord, compare the pin configuration in the diagram to your existing cord or to the corresponding outlet on the side of your control system. Each piece of equipment will have a unique combination.
