Sounds good never had a 4WD let alone locking diffs before! Didn’t know how you would tell.You wire the compressors with a simple on-off switch exactly like you'd use if you were wiring a simple 12 volt light. As I mentioned in my #19 post on the first page of this thread.
The sensors indicating the lockers are locked will no longer work nor are they needed. No other lockers we install into our Jeeps have or use sensors that verify they are locked. You can easily tell when they are locked/unlocked by how your Jeep drives.
