Do you think that the under hood unit replacement will solve the issue , i want to trace the lines back to the ECU
And without the schematic its almost impossible

I don't know how well it is understood from the pictures. And I don't even know exactly if I hit the car's features, you were a bit poor in details.

its perfect , but for the tail lights the whole schematics ended by the Rear Electrical Center REC , further i canot trace them back any more to brake switch for examle.
what you did is perfect but if you can also provide that i will be grateful Sir, thanks alot

The information between UEC and REC is done in Digital, through CAN, only through the CAN bus ... analogically only the information from the brake switch is transmitted to REC.

The problem with the taillights generally occurs due to condensation in the REC, which begins to affect wiring and soldering. Inside the REC.
The REC module is very close to the rear wing, in winter this board is very cold and all the moisture in the car condenses on the cold parts, including the REC
