Does anyone have a wiring diagram (or hard facts) for converting the Lucas to GM hei distributor (HEI Dizzy 55,000v.,early Buick V-8, this is the Ebay one with the tall body). I knew to eliminate the Blue & Red module wires (no longer needed), The White/Green coil wire goes to a new ign. relay to turn on the battery power directly to the hei, but where does the White/Black wire go? This is the one that fools CPU into turning on the Inj. resistors. Otherwise it will start and only run for a minute or so. I've cooked several ign. coils by having this W/B wire in the wrong place evidently.

Here's pics of the Lucas unit compared to the HEI DIZZY, quite a bit taller than stock. Also, the dizzy in place on my 4.2, it is excellent in wet conditions (stream crossings or an good engine wash...), that is... when I can keep the coil from smoking.
