Sometimes, certain things are not easy to understand only by writing. What I understood from what you wrote is that instead of taking the signal in front of FFC, I can use a wire that runs from behind the FFC connector. If so, however, escapes me a thing since the FFC i have to place it over the wire to weld it with hot air, but when the tin will melt the FFC a little will lower and it could create a short circuit between the pads. But surely I misunderstood.
