I am trying to wire a blower motor into an existing duct to increase flow because it goes to a upstairs bedroom.Problem is, the condeser motor has 5 wiers inline motor has 2, which wires do I use on the condenser motor 2 brown capasitor wires,purple wiree going to breaker, red wire going to a relay ?

Hint:

It's not the capacitor, so it must be purple and red will be power to the AUX blower.

Your other choice, would be to add a 24 VAC relay in a junction box where the motor is going to be located and wire the coil side (24 VAC) to activate this relay and take power at a convenient place close to the booster fan location.
