Please help me locate the dropping resistor!

[Donaldo]

The low speed fan is not working on my 126 euro. Thanks to this forum I have narrowed the probable causes down to a faulty dropping relay. The problem is that I can't find it. It is not below the headlight (either one), as identified on many posts. Is this because a euro has it at another location?

The fan power and R/D sensor wires feed into a harness and run up under the fuse box and through the firewall. There are no signs of any wiring exiting this harness at this point. I can't tell how the wiring comes back through the firewall to the fuses and relays. Does anyone know where the dropping resistor is located?Please help me. Thanks.
