I see where P2 is the plug that the wires from the start stop switches are connected to the control board. My wiring diagram does not show The other pins that are inside the P2 plug that you referenced such as P1,2,3,10,11,and 12. Any information as to how to identify these pins would be helpful. P2 has 9 pin spaces but only 7 are used. Looks like 3 for the local start/stop switch and 4 for the remote switches.
On the remote switches, the common connection is ground. The other two connections are to the start and stop inputs on p2. When the start wire is connected to ground, the controller begins the start sequence. When the stop wire is connected to ground, the controller begins the shutdown sequence.
On p2 on the controller, pin 1 is the start connection, pin 2 is the stop connection, and pin 3 is the ground connection. Without operating the switch, pins 1 and 2 of p2 should both measure 12 volts. With respect to pin 3. When the switch is in the either the start or stop position, the respective pin on p2 ( either 1 or 2) is connected to pin 3 of p2.
The local switch connects to pins 10, 11 and 12 of p2.
Hope this helps.
