Hi Sarah, there are`two fuses for the standard Ford radio they are in the fusebox by the drivers right knee, fuse 19 10amp is the ignition supply and fuse 22 10amp is the memory supply, these are fed by fuses in the fusebox under the bonnet, fuse 39 60amp feeds fuse 22 and fuse 40 60amp feeds fuse 19 through the ignition switch, if a copy of the wiring diagram would help contact me on nige110162(at symbol)hotmail.co.uk
