I just installed a used 230Q in my 01 Disco 2. If got it all hooked up and had 2 wires left over. I jumped them because I think it is the Diff lock sensor. When I started the truck I have a Red set of axels glowing, ABS and TC all on. My new transfer case had no place to put the sensor that why I just jumped it out. After reading a little about it I think that this must be the Diff Lock warning sensor wiring? Dose anyone know if the sensor should be left open to turn all that stuff on the dash off. Thanks. Ben
