For the motor you have chosen you will need a Motor Run Capacitor, 7.5 MFD Rating, 370 Voltage.

HELP! LOL. My old fan had 3 wires Black, Orange & Purple. The new motor has 4 wires plus ground. Black, Purple, Brown & Brown with white stripe. The 2 brown have connectors but the black and purple do not. I am going to store to get the connectors for the 2 that don't have them. I am planning to plug the new purple where the old purple was and the new black where the old black was. Then should I plug the brown where the orange was and not use the brown w/ brown stripe? It did not have a wiring diagram with new motor. My unit has diagram with black, orange and purple.

Thanks for your help! I am in deep and would like to finish tonight.

Look at the motor's nameplate, it will show you how to wire it up 3 or 4 wire.
Also, don't forget the verify the proper rotation of the motor and set the windings accordingly.

Thanks. I didn't even think to look at the label/nameplate. But it did get it to work and it sounds great! It's just not rotating in the right direction. It should turn CW but it is going CCW. This fan has the option to go both directions. Before I had cut off the shaft, I tested it to see if it was going in the right direction, it wasn't so I swapped out the solid brown wire for the brown w/ white stripe and I could have sworn it went CW! So I cut the shaft down, adjusted the mounting screws, set the ground wire (which the old fan did not have) and zip tied everything nice and neat and tested it before I set it back over the compressor & it went CCW!? By that time it was dark and I was probably hallucinating by that point so I closed it up and will try again in the morning.

I will look at the nameplate in the morning & I hope it tells me how to get it to go CW. There is a wire harness connector that comes out of the side separate from the other wires, kind of like a loop-back it's white and black wires, I wonder if that somehow has something to do with the rotating direction?

Well thanks for all your help. I hope I can get it to rotate properly in the morning it's suppose to be 95 here on Wednesday.

That wire harness is what changes the rotation of the motor.
Change the orientation of the harness to achieve these results:
From the shaft end, CW rotation is set by Purple to purple & yellow to yellow.
From the shaft end, CCW rotation is set by Yellow to purple & Purple to yellow.

Yes you are absolutely correct!! The first thing I checked was the nameplate and it said exactly that! I just had to pull it apart & switch it from black-black & white-white for CCW to black-white & white-black for CW! All the other wires I had connected were correct according to the nameplate.

Thanks for ALL of your help! I saved about $700+ by doing it myself.

Another successful outcome with help from kok328!!
