Default 04 expedition ac issues

So my belt went Friday an took put the wired on my ac clutch behind pulley. Installed new ac an replaced no11 fuse. Put half can of freon in before starting to make sure it had some in to start cycling. Ac still won't turn on I've drove myself nuts trying to figure this out.
checked every fuse, replaced ac clutch relay an diode in aux 1 location with ones out of my other car. Have power going in an out of high an low side pressure switches. But no power at pigtail at compressor.
also jus to be certain I did power the clutch straight from battery an it does work. What am I missing

Edit also don't think it will matter but did a rear ac block off while I had freon out

Check your owner's manual in the specifications section and there it should tell you what fuse and relay control the A/C compressor.

I did that the manual don't show most of the stuff in this one like the aux1 box with diode an relay mounted on radiator support.an the Chilton book I have that says 97 to 14 expedition all schematics are wrong for my vehicle they don't even match the owners manual
