1969 280S Wiring schematics W108

I am changing the engines out between a 280S and a 280SE, both are 1969 4 door models.
I am looking for a source for the wiring schematics where I can see the differences between the models.
Would appreciate any help!

Only difference is in the fuel system wiring. Carb engines have a connection for the stop solenoids and autochoke and the MFI has a cold start solenoid and a cold start valve .
The cold start valve requires a relay but the wiring should come with the engine.

You also will need to wire in the relay for the fuel pump. and wiring from the relay to the pump.
