1977 280SL Euro fuel injection wiring diagram
 

Guys,
I recently purchased a 1977 280SL 6 cylinder fuel injected M110.982 engine that was running bad. Thinking the problem was it sitting up I took the change at a good price. The problem is that the ECU under the dash went out and instead of replacing it with the correct unit they put a 450SL ECU in and rigged the wiring harness to 6 cylinders. It runs to rich and dumps to much gas into system.
I have the correct ECU but would like the wiring diagram.
Thanks,

as it happens I have a spare of the older M110 engine manual. The old ones include section 7.4 with the d-jet info. -CTH

Are you sure that your car is a 77? It sounds to me like your car should be a 75 or earlier.

Thanks
