(Which gear would this count as?)
It's getting there. The arduous task of re-wiring the Fića can't be completed in a few days, or even a few weeks. When a car's wires are thrown about in all the wrong directions, one's brain has to work overtime to sort out all the permutations.
In this case, it's taking three different wiring diagrams (two "sixes" and an "eight") to find where the wires were (incorrectly) connected to begin with, and then extensive testing on top of that to confirm that everything is where it seems to be.
Only then comes the part where you actually connect the wires properly.
