If there are 3 wires coming from somewhere in the A/C unit (black, red, and white), these connect to the new motor, match colors. The two brown wires go to the capacitor. It doesn't matter which one goes to which terminal. Just put one of them on one terminal and the other one on the other terminal. There will be only one wire on each capacitor terminal of the new motor.
If the motor is energized, wait a couple of minutes before you touch the capacitor terminals. They hold a charge for a while.
If you're using the old capacitor, make sure it's the proper rating. The µf is the most important. It should be within 10% of what is stated on the motor nameplate. The voltage rating of the capacitor must be equal or greater than what's stated on the nameplate.
I usually recommend a new capacitor with a new motor, they're about $10 or so, and if the old one was bad, it'll damage the new motor eventually.
