Hello,
I have a Motec M600 Ecu and i'm trying to wire a coil-on plug using a Bosch Ignition module
The coil reference is Delphi 28211913
The ignition module is Bosch 0227100124

I wired it as illustrated in the attached image.

My problem is that when wiring the coil as described, my injector doesn't works anymore (it works with "test output" function but not when cranking).
I disconnected the GND from the coil (green connector on the image), the injector then works, but as soon as i try to start the engine, the coil is permanently powered (i guess, since i burnt the ignition module)

Does someone has an idea about the correct wiring please ?

thanks

Is that green box supposed to be a diode?

Does that coil need an ignitor? Most three pin coils are smart coils that get driven directly from the ECU IGN outputs.

Hello, thanks for your help
The green box is just here to show the wire i disconnected

I don't know if it's a smart coil, how can i know ?

Looking at the coil schematics, there are three pins : +, GND and - . I don't know what pin should be the trigger pin

If i give 12v directly to + and - of the coil, it charges (so i have to not let those pins permanently powered).
