I have recently installed a 2 DIN Navi, and changed my center console from an old 1 ASC buttoned to a ASC+seat heater unit. This one fits perfectly but the plug from my old ASC button has a small flat 4 pin connecter, the new button unit has the same but with an 3 pin connecter. When I connect it all the lights turn on but I cannot turn off the ASC. I already know what pins are what, but I don't understand why the switch has only 3 pins and how I can make this work.
Does any unit exist with seatheating but with 4 pins?
Thank you for any help
