Most of a day to get the locker controls rewired and attached to the SwitchPros.
The SP has 4 circuits rated for 20amps and 4 rated for 35amps. The 35amp circuits have a pair of wires coming out of the controller. In this instance, I ran one purple to the ARB compressor and the second purple to the switches to send power back to the solenoids at the compressor.

The compressor is an interlock for the solenoids.
This means that when I turn on the compressor at the SwitchPros...

Only then will the compressor solenoids be able to be switched open and activate the lockers. The switches are independent of each other, as well.
When the compressor is turned off at the SwitchPros or the ignition is turned off, the solenoids automatically open up and release the lockers.
The only flaw in this arrangement is that if I do not physically switch off the lockers, then they will lock immediately when the compressor starts up. We shall see if this is a problem to solve.
Halfway done!
