Here is an update, the Lumenition optical eye failed at less than 1000 miles. Disappointing. Now this car is fitted with a Pertronix. I have kept the Loom for the Lumention and the Amp mounted up front, so I can use as a back up. The Pertronix needs less wiring so I hid that new harness under the other one.
The other car has the SNG conversion and is doing fine but has hardly any miles on yet.
