Converting a manual brake switch to a brake pressure switch wiring

Harley's probably aren't driven as much as autos here in the Northeast. Also because they drive between lanes they don't hit their brakes as much in rush hour traffic.
This all started putting in new carpet I was converting to a brake pressure switch from a manual switch now checking all my lights I have no brake lights or running lights turn signals work I noticed a spark when feeding the wires through the fire wall from the manual switch but all the fuses are good ????? I bet I cut something trimming carpet ?? or behind kick panel I'M SUCH A DUMB ***
