Trying to put in hydrolic brake light switch. Painless wiring harness. Have power to plug that goes to switch. When "jump switch", no brake lights. My blinkers were working but also not working now. Headlights and tail lights are working. Last nugget, while installing, grounded power wire for brake switch and blew stop and wiped fuses. New fuses in. Checked all others. Thoughts?? Saw commentary about blinker switch. Where is that located?
