Information 

Select a place for the joint where there is enough space to join all the lines present.

Do not cut the lines too short in case they have to be laid in a different position if there is insufficient space in the area of the joint.

Information 

The electric lines are located in the plenum panel and are thus exposed to the highest demands.

The greatest care must be used in the individual work steps for stripping insulation from, crimping, and shrinking/insulating the electric lines.

The procedure for stripping insulation from, crimping, and shrinking/insulating the electric lines must be complied with and observed. The procedures are described in detail in the Repair kit for Cayenne harnesses NR.155-2  .

Crimping samples are to be prepared before beginning work.

2. 17.2. Slide shrink-fit hoses onto the lines.
3. 17.3. Strip 10 mm of insulation off the lines.
4. 17.4. Crimp the lines using crimping sleeves and the hand crimping pliers  from the repair kit for wiring harnesses Nr.155-1  .
5. 17.5. Slide the shrink-fit hoses over the crimp connections and carefully shrink them using the hot-air blower with special nozzle  (recommended accessories for the repair kit for wire harnesses) so that they are watertight.
6. 17.6. Wrap commercially available PVC tape all around the area of the connection points.
7. 17.7. Secure the repaired area -b-  to the main wire harness with tie-wraps.
