I've turned off the power. But now I don't know what to do next. Got the replacement side spa remote from Amazon and it is a perfect match, with 100 feet of wire already attached. I think I've got to cut the old remote off, attach the end of the wires on the new remote and carefully pull the whole thing through the conduit. Then, at the other end, attach the wires to the Jandy box on the wall. Does anyone have any experience at this?
