Cords and connectors/plugs come in a few different styles. It is very important to match the type of cord and connector that is on your existing keypad when searching for a replacement.
Spa keypads' modular (phone type) connectors
Common type of connector and cord. This type can be found on many different models and brands throughout the years.
These are similar to land line telephone connectors, as well as coaxial data cables for computers and modems.
Available in 6 or 8 pin configurations, be sure to match when choosing a new keypad. (Fig. 1)

Hot tub control panels' ribbon cables and connectors
Commonly found in computers and hard drives is a multi-wire cable where the internal wires run parallel to each other. As a result, the cable is wide and very flat making it flexible and resembling a ribbon.
In hot tub keypads, these are very common with select manufacturers such as Jacuzzi, and Sundance.
Pin configurations for keypads can run anywhere between 8-20 pins, however, 10 and 14 pins connectors tend to be the most common. (Fig. 4)
