/wwwthreads_images/icons/tongue.gif Hmmmm.......the factory diagram that I have shows a three-wire hookup....black is ground....yellow is ign power feeder.....and violet hooks to the duraspark violet wire. That shows clear up thru 1986. Are you sure that is a stock unit? 1974 and 1975 shows a yellow (+) feeder and a red wire to the ignition module. My book doesn't show a 76-'79 for some reason./wwwthreads_images/icons/frown.gif
