I have a coleman evcon heat pump (MODEL NO. BRHQ036B) and the condenser fan motor has to be replaced. I purchased an A.O. Smith motor but the leads are
Different than the old motor. This heat pump has two capacitors, a run capacitor for the fan motor and another capacitor for the compressor. The new motor has a brown lead, a brown and white lead, a yellow lead and a black lead. The diagram on the new motor shows the two brown wires connecting to the new capacitor and the black and yellow lead to LINE. Where do I connect these two wires?

The two power wires (black and yellow in your case) for the fan motor connect to the contactor/starter on the same side as the compressor. When the contactor makes connection on a call for cooling the contactor pulls in and makes connection to the compressor and the fan motor.
