Does shift light use stock tach?? If i am using a shift light will it respond to the stock tach? If so, I assume that the light will be off (inaccurate) just like the tach??

most shift lights have their own programming and you hook them up just like you would an auxilliary tach. it will be running off of the ignition control wires to your pcm (im pretty sure). its like the white #10 wire or something on the bottom half of your comp. it wont be reading the mechanical readings of your tach if thats what you mean so it will be accurate on its own.
