10 Connect black 2-pin coupling (2.1) to free slot on electrical connection for left vehicle floor interior CAN potential distributor (X30/32). 11 Route red line (rt) and black line (sw) through passage in firewall to front SAM control unit with fuse and relay module and fix in place with cable ties. Use a pull-through device. P88.40-3031-06 12 Disconnect orange 14-pin connector (4) at front SAM control unit with fuse and relay module (N10/1). P88.40-3042-11 13.1 Install red line (rt) in contact cavity "6" of orange 14- pin connector (4). If contact cavity "6" of orange 14-pin connector (4) is not used. If contact cavity "6" of orange 14-pin connector (4) is used. Contact cavity "6" is labeled. 13.2 Connect contact spring on red line (rt) and red line (rt) to present line in contact cavity "6" of orange 14-pin connector (4) with potential distributor. Contact cavity "6" is labeled. Take the potential distributor from the basic wiring harness repair kit and the wiring harness repair kit passenger car expansion. P88.40-3043-11
15 Remove cable grommet (10) from housing on front SAM control unit with fuse and relay module (N10/1). P88.40-3045-11 16 Remove cable grommet (11) from housing on front SAM control unit with fuse and relay module (N10/1). Cable grommet (11) is no longer required. 17 Route black line (sw) along front SAM control unit with fuse and relay module (N10/1). 18 Route black line (sw) through opening in housing of front SAM control unit with fuse and relay module (N10/1) and install cable grommet installed on black line (sw). P88.40-3044-11
19 Remove cable grommet (10) from housing on front SAM control unit with fuse and relay module (N10/1). P88.40-3045-11 20 Route black line (sw) from front SAM control unit with fuse and relay module (N10/1) along present lines to installation location of illuminated Mercedes star and fix in place with cable ties. 21 Install black line (sw) into black connector housing (2.4). Contact cavity assignment: - Chamber 1 = white line tieout (ws) - Chamber 2 = black line tieout (sw 1) The black line (sw) is connected to the black 2-pin connector on the illuminated Mercedes star later.
