Can anyone post up the wiring diagrams for the radiator cooling fans, with the low/high speed dropping resistor, relays and such?

I assume it's for the '98 listed in your profile. Here you go.

Here is information from the Service Manual:

Electrical System
NOTE: With A/C ON, the cooling fan motors will run continuously. Cooling fan motors will not cycle ON and OFF with A/C clutch (2884).

NOTE: An exception to this is when vehicle speed is over 61 km/h (38 mph) and coolant temperature is below 100°C (212°F), and A/C head pressure is below 1.71 MPA (250 psi). The cooling fan motors will then automatically shut off.

The cooling fan motors are mounted within a fan shroud (8146) behind the radiator (8005).


Cooling Fan, Electric
WARNING: THE ENGINE ELECTRIC COOLING FAN MOTOR MAY COME ON AT ANY TIME WITHOUT WARNING WITH THE IGNITION SWITCH IN THE RUN POSITION, EVEN IF THE ENGINE IS NOT RUNNING.

The fan control system consists of the following:
powertrain control module (PCM) (12A650)
related wiring
two, two-speed cooling fan motors attached to a fan shroud (8146)located behind the radiator (8005)
powertrain control module
A/C cycling switch
A/C clutch coil circuit
cooling fan motors
The cooling fan motors are wired to operate only when ignition switch is in the RUN position, thereby preventing radiator electric motor operation after the ignition switch is turned to the OFF position.

For what it's worth. There are a number of off-sheet references, too many for me to gather up at this point, and this doesn't do much about telling you where this stuff is.
