well i deleted my DIC and i dont want to put a bulb in the tach for the blue perf shift indicator and i had to make my own button anyway since i switched to a leather grand am shift knob so i wired this up lit rocker switch flush mounted and led indicator is on when perf shift is on and off when perf shift is off...also i put an 11 SMT LED bulb in the shifter light much nicer looking no more pink, gonna do my tach next
