Ok im in need of a diagram or a picture of the fuse block thats located under the dash. Its a UK spec 7 so i know its gonna be different than US spec. For example under the hood ive got 2 EGI fuses. Where as the US spec has one.

Main reason im looking is to locate the wire so i can run an inline fuel switch.


Thanks for the help
Andy

 

See the FAQ for fuse box covers. It will be the same for a UK model.

All S4 FC's have two EGI fuses. S5's only have one.

You don't need to go to the fuse box for a fuel cut switch. It's easier to go to the Circuit Opening Relay that turns the fuel pump off if the engine stalls. It’s a located under the dash next to the steering column and has a yellow base.



The B wire (black with a white stripe) is the power supply and the Fp wire (blue with a red stripe) goes to the fuel pump. The switch can go into either of these wires, it doesn’t matter which. Simply cut the wire, extend each cut end to your chosen switch location using the same or thicker gauge wire and terminate them onto the switch. Note that the STA wire is also black with a white stripe, but it’s thinner. Make sure you get the right wire.

 

Heres a picture. I had the same problem.
Good luck.. Hope it helps.
