ignition pulse generator wire

I have just finished trouble shooting the daylights out of my other bike and I need to know where the ignition pulse generator is? and if it is the same thing as the pick up coil, if so where is that? Thank you

I purchased a GIpro x-type gear indicator for my 2005 VTX 1300 c. It hooks up to the speed sensor coupler which was no problem, but then another single wire needs to be hooked into "the wire that comes from the Ignition Pulse Generator (pickup coil)". Instructions state I can find this wire...
