I Have just about every MB manual published from the late 50s to 1993. To the best of my knowledge there is no 4.5 engine wiring diagram. I do have a one line function electrical schematic for the entire car. what was your concern?

280SEL Wiring diagram

Thanks for your response, my mechanic has been trying to sort out the injection wiring harness on my 280SEL 4.5... We are working off a W116 Haynes Manual right now and he wanted to see the schematics from a shop manual. Fortunatly with help of a distinguished member of this forum and a lucky find at the junk yard, we got hold of two good FI wiring harneses and made some progess. I think we are about 90% there with this car.

It goes to the fuel pump relay, which I believe is on the panel in the right front of the engine compartment by the ECU. I assume you have a w108 V8 car. Send or post your email and I can email you the diagram.

Most of the wiring for the 72/3 280SEL 4.5 would be same as on a 72/73 R/C107. The wiring diagrams are in the chassis section of the shop manual on the Startek sire under Workshop Resources.

This 72 350SL diagram would be close:

Section 07.4 of the M116/7 manual has greater detail on the injection harness wiring.
