Does anyone have or can you point me to a website with the color code/wiring diagram for an '86 745 GLE wagon cassette/radio? The radio has a din style plug in the back instead of the twin row rectangular of the later 740/940 radios. I wanted to put the later 940 radio in the 745 but the wiring and plugs are all different and not intuitively obvious. Thanks! RAFster David
