Exactly what 67Dart273's post says.
To re-iterate, remove the ballast and connect the two wires to it together (dk blu & brn). Also connect the Ignitor's red wire to those. If the red wire is bare, just add 2 male spade terminals to do so. Use the type w/ full insulation, or wrap everything w/ silicone tape.
As mentioned, if you used just the brn wire, it would spark while cranking and die as you release "crank". If you used just the dk blu wire, it would not spark in "crank", but would as you return to "run" position. It might start 50% of the time in the later case, but 100% is better.
