I have a hot springs sovereign that has this 71904 3 button controller but its not hooked up. Where does the phone plug of the wiring hook up to? I have the large black controller on the side of the tub but it won't adjust the heat for some reason so I got it to run with a smaller controller out of a Sumatran tub. I want to get the tub to work like it was designed. Any assistance would be awesome. Thanks.
