If I manipulate the signal wires at the fan's air solenoid, to cut out the 12V signal sent from the ECM, will I throw a fault code?? Thanks in advance for any info, or direction to another thread on this subject.

YES, the ecm throws a fault if you interrupt the circuit.

I have sen guys get a second fan solenoid and plum it in to control it so that there is no faults.
