Hi I've started fitting the auto light wipers. I have connected the kufatec loom to ce plug b pin 33 (Lin bus loom) and plug c pin 28 (backup signal) and lgnition plus and steady plus to the fuse board. Connected the gnd. Activated in vcds (rls) now the head light switch has an extra plug on the old one that I don't no where go's (little plug with one red and black wire). my lights are always on and get an error say auto lights wiper deactive.
