I could certainly do that. The main reason I planned on putting them in the cabin
was because that's where the documentation for the relay and capacitor said
to put them. "Regulator and capacitor should be mounted in a cool place and should
be mounted on the cockpit side of the firewall" The diagram shows the battery,
alt disconnect relay, capacitor and voltage regulator behind the firewall.
Of these, only the battery has a fixed position fwf in a Sonex. I had planned
to put the regulator fwf mainly because that's where Jabiru has it.
As it's drawn now in my schematic, I have 5 wires going through the firewall between
the regulator, relay, and capacitor. Moving the regulator into the cabin
would cut that down to 3: the 2 alternator leads and the single wire from the
capacitor to the starter contactor.
Or I could mount all of these components fwf, which would eliminate all the firewall
penetrations shown and add just the 22awg alt relay coil wire going fwf.
It sounds like this latter way is how you would do it, which means less firewall
penetrations would trump having these components in the cooler cabin.
