So i was installing a new under car LED kit, when some wires from my LED in the air vents i think accidentally got crossed or something and i heard weird electrical 'clicking' noises. so i ran to the battery and disconnected the negative terminal. i disconnected all the LED's in the vents, put the negative back on the battery and no more noise, however i go to start the car and NOTHING works besides the headlights, fog lights, engine start button and El Glow gauges. The blinkers, radio, map lights, reverse lights, brake lights, warning lights in the gauge cluster, the LCD below the speedo all do NOT work. What the hell? I need help ASAP. and thanks in advance to anyone who can help.
