No too concerned about the stiffeners...this was common practice done to aircraft that were upgraded or were going through repairs. This 109 has them affixed randomly throughout. See first photo. This was done to give extra strength and support to the fuselage in general.

Galland's Me109 F4/U had alot of changes and upgrades, as well as TWO access hatches on the left side. This was because he added two MG151 INSIDE the wings (not as gondolas), as well as two MG131 above the engine. These two extra hatches were added to access the necessary "extra" equipment that was required for these new upgrades, as well keep easy access to the MW50 tank. The same was done to his upgraded E model (see 2nd photo).

As aircraft went to repair facilities (and even at factory), much of the equipment was upgraded internally. For example, at factory, ALL aircraft had the complete electrical system installed for wing gondolas as well as gun camera - even when none were intended.

I suspect the reason for finding the MK108 electrical box was due to the fact that as the MK108 was starting to show itself, repair facilities were already upgrading Me109's to the new standard...adding the newer weapons, as well as the electrical systems to support them. Though the MK108 was never installed on your bird, systems to "support" the Mk108 were.
