Empennage: Aft fuselage. Routing L1082 cable through aft bulkhead.

The L1082 cable is supposed to go through the hole in the aft bulkhead.  Presumably so it can power the light on the rudder.

But the cable has a sort of bolus where the black wire is soldered to the white cable's shield.  It's further layered by some shrink wrap.  So it won't fit through the aft bulkhead's hole.

I tried squishing that bolus with some pliers, but all it did was shorten it one dimension by lengthening it in another.  So I took the shrink wrap off and it fit through the hole with just a bit of coaxing (!).

As a sort of related aside, you can pull bushings out to fit things in later that wouldn't otherwise fit (the plans don't have you place the wiring in a good order, so sometimes you find yourself in a bit of a pickle).
