The other way to do the ingnition
Is to cut the thin pink wire at the ignition switch on top of the column
and then join it to the thin yellow which supply's the coil with 12v to start

Then at the coil you use the yellow for 12v and disconnect the pink 9v wire
The yellow gives 12v while cranking & because the resistor is cut out(thin pink wire) you have 12v while running the engine.
