You could rely on the fuse box ... but the problem is youd have to wire it right into the fuse box yourself ..

you couldnt rely on fords foglight wiring im almost positive .. since those probably run at 3 times the wattage and suck up alot more power.

I would say the best way to do it .. if you want to do it that way .. Is try taking the wire / fuse / kit that came with it .. and try going right to the switch.

But this might lead to problems too, cus i dunno about the switch, how much it can handle either .. :P
