I'd be very surprised if the wiring and circuit I've used doesn't include a relay, afterall the wiring has been put there in the loom with the specific purpose of running front auxiliary lighting.
I think by blowing the fuse might indicate that it doesn’t have its own relay?
Re increasing the 7.5A fuse, there is another consideration. It looks like the infamous dash pcb also handles power from the same fuse via the dash sub harness connection. In the event of a failure elsewhere wouldn’t you could be exposing the pcb and traking to the higher current?
Sorry Rog but in the course of this thread have examined wiring from battery to foglights and there is
no current involved running through PCB. There are however a total of four fuses (including main battery one) though and as you have surmised no relay.
I'm a great believer with electrics of avoiding unnecessary complexity and in so doing adopting the
KISS principle. My Land Rover has survived for approaching 60 years with only one fuse and no relays! Admit to fitting new loom though due to insulation degradation
