Hello,

Lots of theads on the above subject.

However, I'm looking for the internal wiring diagram for the Automatic climate control unit or push button unit for my 1989 300ce. Its shown on the diagram as a empty box marked "N22", with two plugs left and right [x1 and x2]

I have one for my 1982 300sd but not my 1989 300ce.
I may have to just extrapliate the differeneces.

Thanks

Brian
