help with duraspark

[vvlance2007]

im about to convert my 85 ranger to a duraspark and i was wondering if i could just use any performance coil in the style needed for the conversion and is this the best way to go about simpleizing the wiring



thanks

As long as the coil runs on battery voltage otherwise you need to add a ballast resistor. The simplest is to use your stock coil and wire it the same as the second colored diagram in the tech library here is the link.http://www.therangerstation.com/tech_library/2_8Duraspark.html If you use the stock coil then the stock motorcraft plugs are the best I hear but I am running autolite single platinum without a hitch
