Mondeo MK3 TDCI 2003: No Power After Turning Key, Dead Clocks & Ignition Issues - Tips Needed

The patient is a 2003 MK3. The car was working normally. After another attempt to start the clocks dead after some time (it was a wet day). No reaction after turning the ignition switch to the ignition position. Dark clocks. After turning the key to the start position, the starter turns normally, but since there is no power supply, the car does not start. The lights work, etc. Only what is switched on from the ignition position is missing. (no additional alarm, the immo works OK. The second key is the same symptom). Since the power is supplied for start-up, it is OK when reaching the ignition switch.
And here's my question. What fuses, relays are turned on when the ignition is turned. Where to start . Assuming that the ignition switch is OK. I was looking for a pattern but to no avail.
I would like some tips, please.
Regards Konrad.

Bad reasoning - not necessarily, these are other contacts.
First, the measurement on the ignition switch.

Ok. thanks for the info.
Do you have a diagram? Ignition and ignition system ?.

Enter the engine type and we'll look at engine control.

See the light that goes out after a while?

Connection block to be checked in a known place

Oki, nothing. Tomorrow I'll check the ignition.
The immo diode does not stop blinking. Because there is no ignition.
The lights don't work, the airflow doesn't work, the clocks are dark. only things that do not require ignition and start-up work. For now, I'm betting on the scattered cube of the ignition ... but holidays, windy, cold and no motivation. Thanks for the info everyone.

The patient is alive. I did not dig into the diagrams, but the fault is removed.
In my case, a whack cube of the ignition (interestingly, after switching to the ignition, the yellow-green voltage appeared). The car in the machine, I only got a cube from the manual, but apart from the lack of a lock for removing the key in a gear other than P, there are no differences. This blockade was previously released and the signal that there is P (even to the controller) was coming all the time. Now it immediately shows the type of run on the clocks. Previously, P.
Two bugs fixed in one fell swoop. Now only young if he wants to, he will replace the ignition cube with the cube from the machine. thanks to everyone for the replies in the thread.
ps.
What's funny is that 2 wholesalers insisted that there was no difference I had to explain to them that it is.
