Splicing the cable

Splicing with insulated damp-sealed crimping sleeve

Illustration A




Select a suitable crimping sleeve according to the cables' area in accordance with the table:






Illustration B




- Strip both cable ends in accordance with the above table. Use stripping pliers, P/N 9512620.

Pressing the sleeve

Illustration A




- Fit the red crimping sleeve in the press tool P/N 9512785. Select the socket as per color coding. Clamp the pliers together slightly, but only so that the crimping sleeve remains in the pliers.
- Insert the cable in the crimping sleeve until it reaches the stop.

Note! Make sure that the cable insulation does not come into the press area of the sleeve or that the stripped part or the cable extends outside of the sleeve.

Illustrations B and C




- Press the legs of the pliers completely together to ensure a proper splice. The pliers will then release automatically.
- With your hand, check that the crimping sleeve is securely in place.






Heating the crimping sleeve

Illustrations A and B




- Place a suitable shield behind the cables to be crimped to prevent thermal stress to the surrounding area.
- Warm the sleeve with a hot air gun, P/N 9512777, and suitable nozzle. It is extremely important that the crimping sleeve be securely crimped around the cable. You should be able to see that a little bit of glue has been forced out around the cable. (Illustration B).





Installing the traffic message channel module (TMC), continued




- Clean the marked surface on the underside of the air duct using isopropanol P/N 1161721. Wipe dry.




- Remove the protective backing tape from the double Velcro fasteners on the TMC unit.




- Guide the TMC unit with the connectors pointing forward up toward the underside of the air duct. Position it so that it does not press against surrounding components, and firmly press it in.

Applies to cars with integrated telephone:
- Reinstall the phone module (PHM) on the underside.
- Torque tighten the two screws to 10 Nm (7.5 ftlb.).

Connecting to the central electronic module (CEM)





Applies to cars with internal amplifier
- Take the adapter cable (1), P/N 30737807, with two small, two large grey and two black connectors from the kit.
- Applies to cars with TMC unit: Plug the two small grey connectors (2) into the corresponding grey connectors (3) in the cable harness from the TMC unit.
- Applies to cars without TMC unit: Take the long cable harness from the kit. Plug the two small grey connectors (2) from the adapter cable into the corresponding grey connectors (3) in the long cable harness.

Applies to all models




- Detach the 32-pin connector in the central electronic module (CEM) by first moving the connector's brace (A) backward, and then detaching the connector (B) upward.




- Remove the secondary catch on the connector by first prizing out both catches at the short sides, and then remove the catch upward. Use tool P/N 9512639.




- Remove the cable from position 20 (only certain car models have this cable connected) by carefully inserting the tool, P/N 9512639 as illustrated, and then disengaging the primary catch while pulling out the cable.




- Dismantle the 4-pin loose black connector from the adapter cable, P/N 30737807. Remove the connector's secondary catch by first prizing out the two catches at the short sides and then pulling the catch outward.




- Plug the cable previously detached from position 20 in the 32-pin connector into position 2 on the loose 4-pin black connector.




- Install the loose short insulated black/white (SB/W) cable for the speed signal on the adapter cable (P/N 30737807) in the 32-pin connector, instead of the one previously removed from position 20.




- Remove the cable from position 5 (only certain car models have this cable connected) by carefully inserting the tool, P/N 9512639 as illustrated, and then disengaging the primary catch while pulling out the cable.




- Plug the cable previously detached from position 5 in the 32-pin connector into position 1 on the loose 4-pin black connector.




- Install the loose short insulated green/brown (GN/BN) cable for the reversing signal on the adapter cable in the 32-pin connector, instead of the one previously removed from position 5.
- Reinstall the secondary catch.

Illustration A




- Take the red (R) crimping sleeve from the kit.
- In accordance with steps 78-80, splice the black/white (SB/W) cable in position 3 from the 4-pin connector (illustration B), together with the long black/white (SB/W) cable in the routed cable harness.

Illustration B





Applies to cars with internal amplifier
- Cut off unnecessary excess from the long black/white (SB/W) cable before splicing.




- Press out and remove the secondary catch on the large black male connector in the routed cable harness.




- Take the short cable with cable terminal (1) from the kit and press it into position (A) in the connector.
- Reinstall the secondary catch.




- Cut off the existing cable terminal on the long brown (BN) cable to ground in the routed cable harness.
- Splice the cable together with the cable in position A in step 96, with the red (R) crimping sleeve from the kit.




- Plug both large black connectors from the routed cable harnesses into each other.




- Plug the two 4-pin black connectors into each other.
- Reinstall the 32-pin connector in the central electronic module (CEM).

Installing the CD drive




- Take the CD drive from the kit. Remove the screw to the adapter, and remove the adapter on the side of the CD drive. Do this on both sides. The parts shall not be used again.




- Take the rubber spacer from the kit and install it on the CD drive.




- Take the bracket from the kit and install it on the CD drive.




- Take two small screws from the kit and tighten the bracket into the CD drive.




- Attach the yellow (1) connector from the screen to the green connector (2) on the routed cable harness.




- Take the new inner glovebox section from the kit. Insert the brown (1), black (2) and multi-colored (3) connector, and the cable with the blank connector (4), through the hole in the rear edge of the glovebox section.




- Take the CD drive with bracket and plug in the connectors:
- Black connector (1)
- Brown connector (2)
- Multi-colored connector (3)
- Blank connector (4). A small click should be audible when this is pressed in and locked on the connector.




- Fit the CD drive in the inner section of the glovebox with the hooks (1).




- Fit the inner section of the glovebox in its correct position.
- Take the screws (1) previously removed and tighten in both the CD drive bracket and the glovebox section.
