Hi, I was wondering if anyone knows, or if anyone could look up on WIS how to install illuminated sills onto a W245 for front doors only. There is a powerfeed for each one, plus a relay and a link up to the door light circuit for each one. I need to know where these plugs plug in on each side. All help gratefully received, thanks. (Dealership will not help me & referred me to WIS, which is unavailable to private individuals!)
