Used it on a box. I see no easy way to check it myself. It is just a item from the menu. Do a search for leak. If you want 9 or 10 of them in specific locations better have some time to kill. I have yet to find a fast way to place them. It is put on map check map adjust leak.
You can set an NPC Group ship that's friendly to have the costume you want with an idle animation of "plasma leaking" I think it's called, though they're not truly disabled, and, if any enemy ships get too close, they'll stop leaking and fight them.
