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?

If you haven't already you may try a google search for the particular
ECM motor you have. The ones I know of are actually brushless DC
motors and the "control module" is what converts the AC to DC. You
can't remove the controller and hook the motor directly to AC. Try
posting all nameplate data on the motor.
