Need "C"Wire (5th wire) for Wifi thermostat.

As stated in title, I do have spare wire in bundle neither end is connected to anything.
My dilemma is i need to know what to connect to in the attic unit for the connection. I didn't see the pretty panel in the videos online I have this
The only labeled connection I found is below, all connected to c are brown. Is that my connection? Is it that easy? (Yes I put the fuse back in.)
Any thoughts?

I believe it is the middle C of the CCC part.
I think C #1 is the fan relay, C#2 is the common (the one you need) and C#3 is the condenser relay.
I think they are all actually commons. With it unplugged and the fuse taken out you probably have continuity across all three of the brown wires that are labeled C.

I had to buy a 24volt ac transformer and wired it up to r and c to get my wifi Honeywell to work. Most need 24vac at all times.

Had the same problem last year. Got a new AC installed this spring and had him pull a new thermostat wire.
I know that doesn't help
