Default AC Compressor not getting signal to kick on, but works when hardwired

Recently reinstalled my AC system. The compressor does grab when turned on, but when I hard wire it it does and blows cold air. At the harness directly going to the compressor it's not getting any positive signal, what are my possible fixes? I've already checked the fuse. TIA

Where is the relay located. I've "Hardwired" the compressor to and it has kicked on but it doesn't have power through the harness.

The relay is in the underhood fuse box. You have to check for power to the compressor with the car running. Don't hardwire AC compressors. You'll end up junking your compressor and or clutch.
