Hi AussieHJ,
Yes that is the module but if you have an old Powertorque mower laying around on the nature strip all the earlier ones had the module on them, if not you will have to buy one. Pity about not having the kill switch wire, means you will have to pull the fanwheel off, you were going to have to do that to get to the points anyway and you connect the module into the wire that connects to the condensor and then you have to earth the module to the motor somewhere
