Welcome to Just Answer.
If you can send me a clear, well focused close up picture of the wiring diagram glued inside of the service panel, taken from straight on, I can mark it up with instructions on how to wire the new motor.
The new motor also comes with a wiring diagram glued to the side of it, I need a picture of that as well... lacking that it gets very complicated you will need a multi meter and few hours coaching to figure out which wire is which on the new motor.
use the 'attach files' link at the lower left of your reply box to attach the pictures.
We can go from there.

I will opt out, it is unlikely anyone else here will want to tackle that without a wiring diagram either.
You will most likely have to call in a real good local HVAC company to sort this out for you, on site with instruments etc, They will charge you $200 or so most likely.
If you want help locating a well rated company tell me which direction you are from the center of the nearest town or city and I can take a look.
