Yes it should, unless you have a sensor very near the condenser to regulate
this- turns on the fan when condenser is hot.  I've seen it both ways, but the
wires were there, meaning it was probably removed. You do have the high/low
pressure switches hooked up, to the A/C clutch circuit, right? Are those the
wires you are referring to?
