I have assumed that you are using the Saxo dashboard switches and A/C blower controller (things can be simplified further if you are not).
8007 is the A/C pressure switch, I have shown only the compressor cutoff contacts connected, the other set of contacts, should really bring on the cooling fan.
8015 is still the compressor cutoff relay (in case of engine overheating) The sense of the wiring to the relay coil will depend on the overheat sensor on the AX.
 To clarify, there should be 3 interconnections between the A/C system and the AX cooling system:
1. The AX overheat sensor should cut off the A/C compressor
2. The A/C compressor enable signal should bring on the cooling fan
3. The A/C pressure switch (second contacts) should bring on the cooling fan (not shown in the diagram in this post).
Thank you for the reply. will pin 1 and 2 work when 3 and 4 is blanked on the pressure switch.
