The summer heat and humidity are still beating down so I can understand you need to get the information needed quickly. I have done some research on your model on the Manage MY Life website and have located the owners manual to your model. While you are waiting for a detailed reply from an expert I have provided the link below. Hope this helps! http://www.managemylife.com/mmh/owner_manuals/1893/ICP-Air-conditioner-heat-pump(outside-unit)-L0522744?brand_name_search=TCA030AKA1

Thank you for using Manage My Life. I have the wiring diagram attached here for your reference.

The control and motor that was on your air conditioner was designed to have two speeds. The replacement motor you have can not accommodate this so the speed control will have to be bypassed so the fan motor can only run in one speed.

The brown wire will go to the F terminal on the capacitor. The Brown and White Stripe wire will go to the C terminal on the Capacitor. The black and white wires will go to the L1 and L2 terminals on the contactor. You will need to remove the Orange wire that is on the L2 terminal of the contactor that goes to the FAN terminal on the speed control relay. There will be three terminals on the relay. They are labeled FAN, HI and LO.

If you need help with bypassing the speed control relay, reply here and I will draw up a diagram for you to use.

I'm not sure what you've done already, so I will go over it as if you are starting from scratch.

1. Discharge the capacitor and remove power to the outdoor unit.

2. Remove all of the existing motor wires and remove all of the wires attached to the FAN SPEED CONTROL.

3. Remove the Orange wire that is connected to the L2 terminal on the contactor and remove it from the FAN SPEED CONTROL. (I attached another copy of the wiring diagram for you)

4. Remove the old motor and mount the new one. Then feed the wires to the control panel.

5. The BROWN wire from the fan motor needs to go to the F terminal on the capacitor.

6. The BROWN wire with a WHITE tracer needs to go to the C terminal on the capacitor.

7. The BLACK wire from the fan motor needs to go to the L2 terminal on the contactor.

8. The WHITE wire from the fan motor needs to go to the T1 connector on the contactor.

This should bypass the speed control and the motor will only run in its normal high speed.
