I  was talking with Glen Powell at the LRP event. He said what he did to
separate the differential locks, was to switch the lines to the center
diff actuator, and run the car open at position #1. Since the actuator
changing states turns on the diff locked-lights. What this is supposed
to provide is position #0 for center diff locked, or position #2 for
rear diff locked. With this change, you will not be able to lock both
diffs together.
