okay, i need some help here.
i was installing my tach, everything was fine until the wires touched and sparked..
now, all the wires are connected
problem is...
the tach does not work, but the light works..
and the lights work only when the car is on,
so when i turn on my head lights w/o my engine on.. it doesnt work..
the speedometer still works n all but not the tach
which fuse is it?

theres another problem... the airbag warning light is on..
its been on since the big cc meet on the weekend when the guys helped me find the rpm wire for the tach..
