Im looking to Wire in a stock electronic Ignition in my 72 Dodge Van.

I have the ECU,Dizzy,and harness.

It is my undertanding that the Black/Yellow wire on the harness goes to the - side of the coil.

Then theres a wire I have to supply that goes from the + side of the coil to the Ballast Resistor.

Then theres one wire that comes from the electronic ignition harness,that goes to the other side of the Ballast Resistor.

The other 2 wires in the Electronic ignition harness are for the Distributor and have a connector on them.

So now that I have the wiring sorted out I need to know what wire goes to what side of the ballast resistor?

My ballast resistor currently has 2 red wires going to one side of it and a 2 wires going to the other side,one is yellow and one is red.

Does the wire I provided to the + side of the coil go to the side where the red and yellow wires are on the ballast,or on the other side where theres 2 red wires going to the ballast resistor?
