Anyone have any ideas where I can obtain a more extensive engine wiring diagram? I have the "Electrical Troubleshooting Manual" that came as part of the MBZ Service Manual CD from thepartsbin but it mostly covers the wiring inside the passenger compartment and only a few engine components. I need to replace just about every wire in the engine compartment due to cracks and wear and I want to avoid the $3,800 cost of a whole new harness. There are also several "after market" adds from the previos owner I'd like to remove but I need to know which wires are supposed to be there and which aren't.

Also I need some of the connectors, specifically the fuel injector connector (purple circle) and 4 terminal connector (blue oval). I would like to fix the connections right, not with excessive red electrical tape like they are now. Any ideas are welcomed.

Thanks

Wiring Diagram

The hard copy of "SERVICE MANUAL CHASSIS AND BODY, MODEL 107 VOLUME 1" has 450 wiring diagrams in the back covering the years 1973 - 1981.

I have also used these for my 560.

I purchased the hard cover manuals through
www.books4cars.com

Hope this helps[;)]
