I've swapped to the locker but there is a hole in the top above the actuator what goes there. I vaguely remember someone saying you can just plug it but I'm not sure. I will post a pic.
There's a part up there that senses when the locker is engaged and turns on the light on the dash. I forget what it's called but you should be able to plug it if you want. I don't think will prevent or enable the locker from engaging.
