I did a reset on the bsi unit , radio is set to uk now , have middle interior light on , when you start to undo the door connector it’s dash board lights up , air con lights up even though ignition is off , even turning on makes no difference, found earth post on inner sill at front both sides , have connected to earth as well just in case , now got another ignition and fuse box cheap , have noticed battery earth has various earths , I put power to electric mirrors and both work but doesn’t like it when I try to put windows up , all black wires in door but connection is coloured lol .
