The second pic is interesting to me. One blue wire from the ignition module, one blue has no connection: pic below.

And another mystery blue wire in this junction somewhere.View attachment 1715885972

I believe the splice might be. I would bet it is the "run" line branching off to the different points. Depending on year, / model, the "run" line feeds off to several points. Ignition box, ballast, voltage regulator, and alternator field, and electric choke if used. I believe 340 six packs had an idle solenoid. I don't remember about small blocks, but the B/ RB cars had an retard solenoid on the distributor for a couple years. There are also some other smog--doo dads here and there in about those years.

Look for key points, such as the bulkhead connector. This is why it is so important to get the "path" of a circuit in your head. I often scribble rough notes as to this, especially in the "new" more complicated stuff like my RAM/ Dakota. Those are incredibly difficult to "chase" because the diagrams are so shopped up and convoluted, and spread all over the blasted manual, LOL

they all lead to this wierd splice thing. Is this factory?
