No problem, glad shes running again, it's actually quite a modern design as all newer cars use the flywheel, you are correct they sense the flywheel there is a period in the flywheel which the sensor can sense, this represents TDC (Same principle to 36-1 crankshaft pulley older cars used) If it is the sensor side connector then a new sensor would have this, but if it's the car loom side connector which from what you saying it sounds like then it's a little harder and the mod you have done will suffice.
