Just FYI, the new locker harness you are ordering will have a hard plastic (similar to ARB air hose) breather line in the loom with the wiring. The hose is meant to be inserted into the short stub of rubber hose you still have on your locker actuator. It extends the breather at least as high as the top of the frame (same level your stock diff breathers should have been...) Of course, it doesn't hurt to extend it further than that, but the fact that the stock breather is already secured in the wire loom is pretty handy. Your rear locker harness should also have a breather hose in it.
