What fuse

[Benproducts]

Hi all, just need a bit of advice,
I want to fit a Nokia car kit and need an ignition
Switched live, now I've got the piggyback fuse (add a circuit )
Does anyone know which fuse in the box is switched.

isnt it easier to find the plug coming from the cigerette lighter and solder the wire to the ignition cable?

Looked at that option but didn't want to chop wires or use scotch locks , that's why I got the piggybacks for the fuse box but thank
