Don't have a diagram (anymore) but can assure you the wires go directly to the "igniter" a small black box that provides a switched DC signal to the coils based on data (simple pulses) it gets from the pulsing coil down by the crankshaft. The igniter adjusts the ignition timing based on engine speed. If you have no spark, it could be the ignitor, the pulsing coil, the fuse/junction box, a fuse, the ignition switch (though if it were that or the fuse, you'd likely not get any cranking either). The most commonly failed item is the pulsing coil. Check the pulsing coil with an ohm meter. If it reads infinity, it's bad. They are not too expensive or difficult to replace.
