1. Contact connector (2) of adapter line (1) with the coupling of the vehicle's own radio wiring harness.
2. Route adapter line (1) in as space saving manner as possible in the left lower radio recess.
3. Fix the coupling (3) in position with sufficient gap in the radio recess.

   The adapter line (1) must be routed and fixed in place so that vibrations and damage are ruled out. This must not adversely affect the removal/installation of adjacent components.

4. Route and fix in place the line lacing with the coupling (on control unit) (4) in the front passenger footwell.

   The coupling (on control unit) (4) will be contacted later with the control unit.
