Sorry - it must be me.
I've read the manual, searched the internet, removed the drivers side panel under the glovebox, lain on my back with a torch to locate, on both the front RHS and LHS, but I cannot find the second fuse box/panel. ( Not the main one under the bonnet, the 'other' one. )
Any wisdom for my standard RHD RX300 Gen 2., greatly received.
Happy Boxing Day.
Piers.
