Fuel will come out of the injectors, like most its a fail safe system, if something fails it will still operate, basically like K Jetronic (XR3i) no enrichment though, and it runs like a bag of poo cold, and wont boost properly. I left the earths off once without noticing and it was a nightmare to start cold, although wasnt as hard as some people find it to be.

I'll double check which fuse it is i always forget, im sure its that one.

The brown thingy can be seen in this picture although i cant remember which slot its in on a S2, as you may notice this is a MK3 fusebox (MK3's dont normally have this )
