from other post looks like it draw 10amps on 3 hi
I have always wondered why it was not a variable speed switch just seems I
can never get the air flow the way I want it
also thatt switch does not use any resistor to control the dc motor speed it
uses a power pulse modulation to control the speed
also it comes in kit form you can mount that unit any where you want lot of
space for that
the only issue is can i get access to the negative lead of the blower w/o
ripping out the dash
