I´m installing a tach and I can´t find the electronic ignition box.

Do you have an lx, pony, or gt? I have a how-to for lx/pony tach hook up on my web page. Link is in my sig. If it´s a gt there should be a wire off the coil that you connect it to.

It´s a gt and could you help me with which wire I plug the signal wire into on the coil

ahh you plug it into the MSD Box ? sorry....well if you go to the coil I can save you time and tell you the blue wire is the positive and the yellow striped one is negative...and its the negative that actually fires the coil.
