If you look again on the wiring diagram you purchased from me:
I believe there is a note along-side the 1 wire alternator installation detail clearly saying that the alternator light is no longer functional with the one wire alternator optional installation.
That warning light circuit is derived from the old alternator and voltage regulator system design, both of which are no longer used with a single wire alternator setup.
This applies to all 3 versions of my Superformance wiring diagrams...
If you find a way to make it work I would appreciate you letting me know so I can update everyone’s wiring diagrams....
Anyone with a copy of my wiring diagram can always contact me directly about issues like this. A card with my email was enclosed with your wiring diagram.
I'll update the note on all 3 SPF wiring diagrams so this is clearer for everyone.
