Dewert Ultra Control Box Replacement. This wiring harness Set Up Comes With A New Style Power Supply And Connecting Cables For Your Motor and Hand Control.this is less expensive than the original part and similar to the new power supplies in use today. Please view details and view the photo for connection instructions. You will only use your motor and European Dewert hand control over again. You will not need any other of your old cables. Simply plug this 3 wire harness into your old motor (ie. Megamat MBZ) and into your hand control and into the new power supply. The new power supply will have a green LED indicator light and a place for 2 nine volt batteries for battery back up if the power goes out. (If your chair will go up but not down or down but not up you probably have a bad hand control and not a bad power supply.)............ PLEASE VIEW SECOND PHOTO FOR CONNECTION INSTRUCTIONS...This item is a savings over the original part and is checked prior to shipping. Please be careful to hook it up right. It is not returnable.
