I found the electronic spark control sensor but don't see the module, from photos I'm certain it is a five wire connection but don't see anything that looks like the module photos. ("electronic spark control" is more commonly known as "anti-knock" and is not the same as an "ignition control module")

Thanks for trying but I've had no success in finding the module, I plan to just replace the sensor and hope for the best. Phil
