Power 12v is always to fan motor via 40A fuse and red wire to motor but brown wire from motor to high speed relay and low speed resistor gets grounded by either relay when radiator switch grounds relays according to radiator temp or a/c freon pressure.
Here is wiring diagram for 164 Euro Super for cooling fan. Same as USA version it appears.
But second picture is from 1996 wiring manual so maybe your car has 50A fuse set up? Haven't had time to see where that one is located. It maybe same place on false firewall.
