wtb 123 wiring diagrams
 

I would like to obtain electrical wiring diagrams for the MB W123's I have: 1977 240D, 1983 240D, (both 4sp manual trans.) and 1985 300D Turbo. I have the MB engine, chassis (v1 & 2), and HVAC service manual, (multiple copies of most of the books) and a wiring diagram book for 1978 thru 1980 cars. Photocopies or digitized files are fine. Dealer says they will sell me $150 disk that may have what I want, but reluctant to go that way. I will be happy to share the diagrams that I have.
Thanks

The Haynes Diesel 123 Series repair manual has wiring diagrams through your 1983 240d.
