Dennis,
This is a variable reluctance or magnetic type .... there are no points. There must be an ignition system (box) that is in your car somewhere and you need to find it ….. or possibly this sensor can drive a coil directly but I doubt it. I don't recognize this configuration it might be a European design not common the U.S.
Follow the wires from the distributor and let me know where they lead to. (a pun)
I did not suggest you have the tach tested and I hope it did cost much … we weren’t ready for that step yet.
