I have a furnace blower I want to use as a shop exhaust fan. It's a
GE ECM motor meaning it has electronic controls mounted on the motor,
however, you can remove the control module and behind it are three
wires going to the motor, black, blue, red. There are no other wires
coming from the motor. There's also a capacitor mounted to the
housing. The motor says it's 120/240 volt 1 HP. I have 120 juice
close to the motor and I have a 220 outlet for band and table saw not
so conveniently located but presumably I could tap into that if
necessary.

So, which colors on the motor connect to which colors in the home
wiring?

Which color wire would go to the capacitor?

If I have to tap in behind the higher voltage outlet what's the best
way to work in an on/off switch other than using the breaker as my
switch?
You can't use that motor without its electronic controller and it may be
rather complicated to figure out how to use it even with the controller.
Incidentially, my son recently paid about $400 for one of those controllers
and the whole motor would have been close to $800. So you may want to find a
sale to someone who can use it for its intended purpose.
