I have been searching on my phone, can not find it. But if you think about it, there is a tiny little coil in the electronic distributor and the rotor passes it, it creates a signal. A plus and a minus that goes through the two wires to the ECU box. Now, if you manage to find out which of the two wires to connect via a resistor to the car battery, and then connect the other side to the points, you will have exactly the same signal to the ECU.
