I am planning to do a duraspark electronic ignition conversion in my 67 xr7. Does anyone have any tips or wiring diagrams on this conversion? (I already had the duraspark stuff from another car, so I don't want to use the pretronix stuff) I would like to bypass the pink wire, but not cut it, so that i don't have a weak spark, retain the use of my xr7 tach and use an aftermarket coil. Any ideas on how to do that?
