Gee. I feel sort of cut and shot here. I have one dating back to around 1964. It has 2 wires. One plugs onto the spark plug tip, one plugs into the spark plug wire boot and I set it on top of the starter solenoid so it focuses on the flywheel cutout. No induction, no programming, no adjustment, no problems, no imagination, can't use it in sunlight, though.
