PLEASE NOTE: The pages of this Electrical Troubleshooting Manual or ETM were taken from a 3-ring binder that Mercedes-Benz put out with the ETM's for several different models and years, which would be OK for a repair shop.
I separated them into each section, which has a few years for specific chassis models. In so doing I could sell for less and only what an owner of a single year and model may own.
The ETM pages are genuine and original Mercedes-Benz from the manual and are NOT copies.
I created a binder for each model for protection, but would suggest putting reinforcements around the 3-ring binder punched holes. They are as they come from Mercedes-Benz and were a weak point.
This particular manual covers the 1986 - 1988 124 chassis gasoline models 260E, 300E, 300CE, 300TE with supplements dated 06/89 inserted.
This has all of the electrical wiring diagrams and component locations for the engine, chassis and body on the models listed used in the Tempmatic Climate Control System.
I do not believe this is available from Mercedes-Benz any longer, in any form.
