I would put the wires back into the thermistor. This is what runs the factory installed fans when the temperature gets above 100 degrees (I believe this is the set point) and will give you extra air flow.
Just wanted to circle back Rex and let you know I just ordered the 3 parts you suggested from Amazon, thanks again, now I just have to find my old thermistor to see about replacing that while I'm at it, anyone have a link on line for that ?? Thanks very much
