Where did the wires come from?

Customer: replied 8 months ago.
The wires are coming from the transformer, capacitor, and limit switch. I had to replace the molex 9 pin connector. I have the wires placed as they were running into the male end from the fan motor, and thermostat.

Do you see the wiring diagram on the unit?

Customer: replied 8 months ago.
There isn't one. It looks like there used to be but it isn't readable now.
Customer: replied 8 months ago.
I added a picture of the wires above.

I did not get any pic?

Customer: replied 8 months ago.
It is attached to the response at 10:34. Have to click on the image.jpg hyperlink. I'll attach to this one as well. The wires left that I haven't been able to connect are seen in these first two pics orange, yellow, green, and brown. You will then see a pic of the male portion of the 9 pin connector which is wired as it was before removing everything. I just need to know what wires to combine and wire to the female end of the connector.

You would need the wiring diagram to get that correct./
