Random Fuse

Wonder if any one may be able to shed some light on this random fuse I found today whilst hard wiring my sat nav in (was half way through when I took this photo).

If you look on the photo, follow the earth wire down and there is a horizontal orange fuse which has its own plug, which is itself velcro'd to the fuse board. There are wires coming out of it and they head off under the console toward the radio but I have no idea where they end up and dont fancy ripping it all to bits to find out.


Anyone seen anything like this before?
