I have a different flow switch problem. My switch is installed but prior to plugging it into the panel, the *&(%+$ Dog gnawed the wire and bit off the telephone style plug. I called Goldline and they wouldn't tell me which of the pins are used. All I have to do is splice a new cord to the remainder of old one. The lady at Goldline said "oh, you can't do that and the only solution is to replace the whole thing. $150.00 plus $10.00 shipping". Wow... Anyone know which of the four pins are connected to the two wires.
Thanks
Herb
