Genuine Meyer Touchpad Controller, has square (rectangular) 6 pin plug on end as pictured. Will NOT work with older round plug harnesses without an adpater. This is the newest design with self diagnostics. The red Monitor light will blink a code. Turn the controller over and read code list to diagnose. ****WARNING: NO RETURNS ON ELECTRICAL ITEMS!**** We have (3) and they have been tested to ensure proper operation on 11-11-20. When these 3 are gone that's it. There is a known issue with this part, and until it is resolved we will not sell this part.
