To expand a bit upon my previous reply, the Flamethrower is a round can coil, so no external resistor is needed. If your existing electronic ignition uses a round can coil, installation of the new system will (of course) be easy. If not, you'll have to modify your existing distributor/coil and find a place on your tractor to mount the new coil.
