@el_freddo the "two black things" behind the RH Strut Tower are Vacuum related, can see the Vac lines leaving them from underneath. Cannot recall off hand what they are for...
The Black Box with the Blue Plug, labeled Mitsuba, or something like that, is 3rd Eye Related.
The Black Box on top of the Coil is supposedly an Ignitor, however it has an additional Loom that connects to the Distributor. This is NOT typical on any of my Subaru's here that I have seen. The only thing I can compare it to is the "SUPER Coil" that I have seen in Accessory Parts Catalogues in the "Awesome Older Gen Photo Thread".
I think what it does is read the position of the Advance in the Distributor and (recurves?) the Ignition Timing for the Load/Throttle Position, etc. at hand.
