Can anyone help with the wiring of the switch for the compressor? The electrician wired a 50 amp 220 circuit with 2 hots a neutral and a ground. I know the hots go to 1L1 and 3L2 but where do the neutral and ground go?

What is the voltage of the coil in the mag starter? If it's a 120 volt coil you need the grounded conductor ( the neutral) to go to one side of the coil and you will use one leg of the 240 (so 120volt) to the pressure switch and then back to the coil. The grounding conductor ( the green/bare wire) goes to the can of the mag starter, to the compressor motor frame, and to the pressure switch. If the coil is 220/240 volts, you don't need the grounded conductor to run to the compressor, but you need 4 wires plus a ground to the pressure switch ( 2 in from the hot side of the contactor and 2 back out to the coil)
