Are they wired as front fog lights with a switch on the dash?
No they're not.
Okay well this has surprised me.......
I had a look behind the speedo etc and found the relays and as stated, they weren't labelled. Thanks for the info. But I also found a toggle switch on a bracket which had at some stage been bent up behind the dash (I have one of the bespoke Borghi dashboards) which as John V6 correctly ascertained operated the front lamps which are foglights not spotlights. Before anyone says look at the glass, I have one with foglight glass and the other with spotlight glass just to confuse things.
