The advantage of this method is that you can try it without any damage to the system. Once you've tried it, you'll never connect it again, with the exception of the MOT.

There are 2 connectors on the fluid reservoir. The one on the outside is the normal connector for low fluid detection, the one on the inside is the ABS connector. (Assuming you have a left-hand driven car.)
