Motronic ML4.1 wiring diagram for 164 12v engine

Hello all

I am installing a 164 3.0 12v engine in my ferrari dino 246 replica but am struggling with some of the ecu connections for the ML4.1.

Does anyone have a wiring diagram for the above?

In other questions... Why does the motronic relay have a diode in series with the coil? This could only be to prevent the relay being energised by reverse voltage polarity, but as one side is directly connected to earth that seems a little strange.
So I am replacing te motronic with a more standard 40A double NO relay and wiring in a diode on the negative side. Anybody see any issues with that?

Thanks and congrats on a great forum :)

If you go to the electrical form, the sticky at the top is about wiring diagrams. Jim (papajam) has many if not all, wiring diagrams.

Sounds like a great project. Are you going to start a thread on it? Are you going to call it a 306?
