There are two modifications that I'd like to make to my '85 380SL. The first is a "One-Touch" window Up or Down switching and the other being a remote door lock/unlock feature.
This question is for the Auto window feature. Has anyone done this? I found one module that facilitates this need however, it states " This unit will not work with some German cars that have negative window motor switches." Does the 107 use a "negative window motor switch"? If so, any ideas of alternative options?
