Need urgent help this is really annoying me, was fitting led lights this morning and testing it with the front light plug unplugged and with ignition on touching the wire against the contacts to test led's on off side, when i tried the same with near side the led's wouldn't light up, so so tested off side again and that would't light up now, what is wrong all my normal lights work as normal but the contacts on the plugs that i need for the led's aren't supplying any power, is there a fuse that i have blown, and what is the best way to wire these led's as they need seperate 12v supply.
