I just bought a running 1982 240D and a 1980 240D for $500 bucks. Awesome. Now I'm trying to install the cruise control from the non-working 1980 into the one i drive (the '82). First off does anyone know if this would be possible? The '82 never had it but I found the wiring harness for it, but it has two extra wires and two others are different colors. I've tracked most of the wires, but need to know if it is even possible. Thanks for any help. Diagrams?
