This is the layout for all the mini, maxi and relays for the fuse panel of the C5.

Print out and fold up to put in the fuse panel so you have it handy

Good time to put some spare fuses in the slots for spares and make use of circuits, fuses or relays if your not using them such as if no AIR smog pump then the 2 replays and fuse and that circuit could be used for other purposes.

Those that have voltage to them 24/7 are :

Mini fuses : 2,3,4,7 & 23

All Maxi fuses including the spare locations.

This means any coil of relays to any of those would also be hot 24/7.
