IMPORTANT Because the given opening in the center console is too small to route the iPhone wiring harness (4) through the opening in the stowage box, the black 18-pin coupling for the iPhone wiring harness (5) has to be disassembled.

The black coupling for the iPhone wiring harness (3) cannot be disassembled.

  1. Unclip covering (5.2) for black, 18-pin coupling of iPhone wiring harness (5) from iPhone wiring harness (4), remove and detach iPhone wiring harness (4) from coupling insert (5.1).

    NOTES Do not damage the individual pins, as otherwise it will be impossible to plug them into the coupling insert (5.1) and a new iPhone wiring harness (4) will have to be installed.

    IMPORTANT Additionally mark transparent lines with adhesive tape and label according to their contact cavity assignment.

  2. Wrap insulation tape around the ends of the lines for the iPhone wiring harness (4).
