Everything is color coordinated, now will it make Spark???
Remember this is a Waste Spark ignition system, so Both plug electrodes will need at least platinum, (better still center electrode fine-wire iridium enhancement). as iridium has a much higher melting point than platinum), so spark gap will remain in spec Much longer on Both the center & ground lug side-wire, to prevent spark gap erosion quickly opening the spark gap out of spec on plugs Without enhancement. Also, as this system fires the plugs Every rotation of the crankshaft, once on the power stroke, then on the next crankshaft rotation on the exhaust stroke & half of the plugs get a Reverse Polarity spark that emanates from the ground lug side wire to the center electrode (hence the need for platinum, or iridium enhancement on the ground side-wire lug too), & the other half of the plugs get a normal polarity spark that emanates from the center electrode to the ground side-wire lug. So with this system firing the plugs on Every rotation of the crankshaft, the plugs, wires, coil-pack & coil-pack ground switching transistors design need to be able to take the Double workload of being fired on Every rotation of the crankshaft, the reverse polarity spark & last a long time!!!
More thoughts for consideration, let us know how it goes.

What's wrong with the old drain line in the photo??? Think I can see 3-4 flat mash marks but not too bad & maybe a blow out in the center of the photo where the angular dark looking line is, but I can't really tell what might be going on there from the photo???!!!
