I'm converting my Firebird from a Mallory Electronic ignition system back to a stock distributor (maybe crazy but my Mallory is more for racing). I've heard of a "resistor wire" that attaches to the positive side of the coil. Does anyone have info about this wire? I checked out the wiring diagram and see one pink and one yellow wire but nothing indicates anything special about one of these wires. They currently appear to be attached to a ceramic block in the Mallory system. Is there a way to test if a wire is a resist wire (possibly measuring the resistance)? Any help and info is much appreciated. Thanks Dave
