So I tested this key-window-up/down feature. Its delicious.

I like it.

It'll be wired into the keyless entry system. I also want to install a switch on the dashboard to perform the same actions. I dont know why MB didnt!

From initial inspection, it looks like I'll have to provide power to this convenience relay.

I did notice that only my windows went up/down. My sunroof only closed after I'd opened it. I turned the key on, then off, closed my door, put the key in and held it to unlock, all 4 windows went down. Same was true for lock, except they went up.
