are these set up for 3/8 lines?

No this valve is only for 1/4" air lines

Does this switch have 3 ports for air lines and does it have a slot for a 4pin electrical connection?

No this one has two barbed fittings on the backside for 1/4" OD Airline/ Tubing only. The barbed fitting ports are marked with supply and delivery on the back side. The one you are looking for is with two barbed fittings for 1/4" OD airline and one electric switch to turn ON and OFF your compressor. That one is not listed on Amazon.

If i hook my compressor to my air tank, air tank to switch, switch to airbags. When i push the switch down, will it only drain my air bags of air? Or

No it will also allow the air to go thru them and fill your bags (car go up). The difference with these are they do not have. A manifold or solenoids. The air releases at the switch/valve. Mine is a very simple setup. 1 Compressor, 1 Tank, 1/4" dot lines, valve switches and air bags. Some connectors and It's and I do what I need. I have a 79 El Camino and it lays down and goes up nice and slow.

Would it be possible if I could see the backside of this switch
