1970 250c Mercedes

Hi I have a 1970 250c Mercedes and desperately need a wiring diagram for my power windows, the whole car actually. I already have the haynes book - which doesnt tell you much about them. If any one know where I can get on free or cheap please let me know. I also need a honest transmission mechanic that lives in the california area. My merc wont come out of 2nd gear - acts like it wants to bad. RPMS are up there, I can only go like 30mph. Someone told me it could be the throttle arm stuck??? HELP

I am a woman but I do know my Mercedes Benz well.
