Mopar electronic ignition wiring schematic question

This is from MyMOpar. It is correct except it does not show the bypass (IGN2) circuit which is unchanged, anyhow. Notice at top right it says "splice" and "new wire". This is spliced into the existing ballast power supply wire from the key. So basically you leave the ballast / coil alone, disconnect the points, and hook the wire from the ECU up to the coil NEG in it's place
