Replacing Nordyne PC 621829 MTR 1/5HP 3SP with Mars 10464

I am looking for the wire diagrams for these 2 units. Is there some sort of holy grail of HVAC motor wire diagrams somewhere

The nordyne motor being replacing is coming out of an older gibson unit in one of my rental properties. I'm heading over there in a few hours and I can post some photos, just wanted to get a head start before I got onsite.

Hopefully you ordered a new capacitor for your new motor. You can reuse the old one IF it's the correct value. The new motor should come with a diagram.

The 10464 is a 4 speed 208-230v motor.
White - line
Black - high
Blue - medium high
Yellow - medium low
Red - low
Brown and brown/white - cap
Black/white plug - direction

No diagram found for a PC 621829 motor.

Thank you. So yes I went by and replaced the capacitor which got it working for a bit for a few days until last night. The old motor had 3 brackets soldered onto the motor and the new universal motor did not have any mounting hardware so I went ahead and ordered the actual nordyne motor which arrives tomorrow.
