A bit of an update:

I think I overcharged the system. I put the gauge on the low pressure port without anything running (engine, ac, etc..). The pressure read ~65psi.

I released some of the refrigerant to bring the pressure down to ~50psi.

I then started the vehicle, ran the ac system on full blast with the pressure switch still bypassed and measured the pressure with the system running and had a reading of 28psi.

I then shut off the vehicle, re-connected the pressure switch, started the vehicle and ran ac system on full blast. The compressor engaged and I have cold air blowing out of the vents and a pressure reading of 28psi.

Outdoor temps today are around 70 degrees.
