	Install
	The old headliner (1) serves as a pattern for the wiring harness routing
1	Place new headliner (1) on a suitable clean base
2	Place suitable clean spacers, e.g. foamed material pads or Styropor pads under the new headliner	Do not use any hard or sharp-edged objects otherwise the cover of the new headliner (1) will be damaged. The foamed material pads or Styropor pads prevent the new headliner (1) deflecting during the following stages.
3	Clip the illumination for the left vanity mirror (E14/1) and illumination for the right vanity mirror (E14/2) into the left and right installation frames
4	Contact the wiring harness for the vanity mirror illumination (3) at the illumination for the left vanity mirror (E14/1) and illumination for the right vanity mirror (E14/2)
5	Unclip covering from the left and right pivot bearing of the sun visor (4)
6	Install left and right pivot bearing of the sun visor (4) in the headliner (1) and clip in covering
7	Route wiring harness of vanity mirror illumination (3) and bond to the headliner (1) using strips of adhesive tape which are approx. 10 cm in length, as shown, at intervals of approx. 10 cm	Tesaband 4657	*BR00.45-Z-1071-02A
8	Measure overhang from main wiring harness (2) to the C-pillar from the old headliner (1) and transfer to the new main wiring harness (2)
9	Route new main wiring harness (2) starting at the C-pillar of the new headliner (1) and bond to the headliner (1) using strips of adhesive tape which are approx. 10 cm long, as shown, at intervals of approx. 10 cm	Do not cross over main wiring harness (2) and cable set connections, press on adhesive strips adequately, otherwise a short-circuit can occur due to chafing on the roof paneling.
