As of 2018, the manufacturer has discontinued the old remote and this listing is for the 2 piece conversion kit (Control box and new power supply and a new remote). You will be required to unplug four cords from the old control box and plug them into this new kit. This original remote had a rigid sides for the nuflex or a button on the top edge for the Softide. All 3 have been replaced by this kit and functions wil be the same with the exception of more than 2 massage motors (we sell adapter splitter cables if needed) and lumbar motors (we sell a premium kit for that if needed). We also have a kit avail. for $50 less... let us know if interested!
