Where does the C wire go in the A/C – Furnace

hvac

I know there are similar questions asked but I can't make sense of the diagram in mine. The wire was already run, and you can see the small blue wire hanging disconnected in the picture. Diagram attached.
I'm not not sure where to connect it in the combo A/C – heat unit.
Thanks for any help.

Unfortunately I can only post one picture…so please try to explain as you would to a child…

It doesn't look like your unit exposes the C wire directly, so you'll have to run your own wire from the transformer. Not sure where the transformer is physically in your unit, but here it is on the schematic.

You'll notice a terminal on the secondary side of the transformer, with a bunch of blue wires connected to it. This is the C terminal, and where you'll want to connect your C wire.
