Today I was able to remove the instrument panel, heater and the a/c unit. Found out some new information.
Wiring for gear selector were tejped with a black tejp. In the curve you can see the yellowish paper tejp. On the backside of the tejp there is evidence of paper. The tejp probably holded some kind of information for the assembly staff. All clips for wiring harnesses were added before the paint. The black phosphated clips for optional equipment were all black phophated and added after final paint.
