Here is a diagram I made of where all the wires come from/go to. 2nd diagram I tried to make it not so jumbled, with not much success I'm afraid.
3rd picture is a picture of control panel that shows the parts I am referring to in diagram 1.
I have continuity in the command center plug between the black wire from pressure switch and red wire to right side of contactor (coil?) when I turn the thermostat knob up (on).
So, the orange wire from pressure switch must go somewhere to allow power to complete to left side of contactor? (coil?)The left side of contactor is all white wires.
This is where I am stumped, as to how to complete the circuit from the pressure switch.
I did not do any power on testing, just power off continuity.
On the diagram of the command center plug, the actual colored wires com from the top (female end) but correspond to the pins shown on male end, that comes from/goes to command center.
Kind of messy, but I tried to draw it best I could.
