Mondial T Oil Cooler thermo switch

It seems, according to wiring diagram that thermal switch controlling oil cooler fan has not some relay and the current of 6-8 Amp required by the fan is directly switched through the thermal switch. Am I wrong? Anyone with relative experience? In the diagram 01512 is the cooling fan, 03062 is the thermal switch and 04000 is a combination switch witch seem to be the multi switch used for lights etc. It is strange why positive wire is coming from there but this is how it looks...

 

I am using the official WSM for Mondial T, however its true that there are mistakes and discrepancies indeed. The relays reference is incorrect for some of them, also it is mixed with 348 WSM, i.e. the WSM indicates a second fuse box at the passenger footwell which simply does not exist on Mondial T! In the footwell there are only the ECUs for suspension and A/C, a special relay for time out delay in cabin lights and several connectors. The fuses and relays are mainly to the rear baggage space for the control of fuel pumps etc. It's really very frustrating for an official WSM to have such mistakes.

Now regarding oil fan cooler, it seems that wiring diagram is correct. I have verified through wires' color coding that the diagram (at least in this particular case) is correct . I agree that 1mm2 wire is not the best considering also the wiring length and unavoidable voltage drop but that's it.
So, I decided to add locally a simple relay to relax the thermal switch from the starting/operating current of fan. It is interesting also to mention that the thermal switch is externally fitted to the oil cooler so the sensing temperature is in the back side of the cooler and not the real accurate oil temperature, also I test it and it starts to operate exactly at 80 deg. Celcius.

 

Thanks for the comment, essentially you are right. If you see my previous comment is an update which clarify all points.
