marlowe,
I will e-mail you a picture of how the wiring is to go on a Superformance. I install mine on #992, and this worked!
Suggest changing dist, coil and ignition all at the same time, use all the same brand matched.
Also, my suggestion is to place the 6AL under the passengers foot box, not where the Duraspark is now. (Mount it upside down, inside the cockpit, above the passengers right knee estimated).
Any other questions, ask away!
Eric
