Power supply 5V in the ECU?

[El Berto]

Hello all, so I had to open a different ECU (all FIAT group) and I are often asked for a thing: but where the hell is the power supply 5V?
I have not noticed chokes, so I suppose it's a linear regulator.
By controlling the various components, I have found nothing that could even remotely resemble a 7805.
Then someone of you would know by chance tell me how to pull out the 5 volts by a control unit Bosch Motronic?
Thanks.

definitely will have voltage regulators that look like small integrated

I don't know if it can? to be useful, but I found this diagram of a control unit for multijet that perhaps reveals some component feeder type or another. I don't understand the diagram but I see that ? rather detailed.
