Shaggy,I thought of going strait to the fan motor too.Only electical work isn't my strong point.I didn't want to take a chance burning up the fan motor.I can read a diagram and schematic and follow directions very well though.So when I came across that tech note at
http://www.brothersperformance.com I thought it was a pretty COOL idea.It was very easy to install the switch.On high speed it don't take very long to cool down.Less than 5 mins.I haven't seen any street stangs at my local track cooling down between rounds.Just the hard core guys who trailer their rods.Most using 115 volt blowers.I thought some of you guys might find this info usefull.#17 pin to ground turns fan on,who woulda thought.lol
