Well I just received my ZKW today, and as I thought when I read your post, that bulb is not an H1, that is a low wattage bulb for the "daytime running lights" the reason it was disabled is to be able to use that connector for the DDE connection. BTW does anyone have the instructions on the installation of the HL, I need to know what pin is what. If you look at the car that someone was trying to buy, that car has the ZKW with no DDE option and it does have the DRL on. Again please someone help with schematics on the pins 1-4. I will post pics soon.
