- The number of plug connections can vary, depending on equipment.







Preliminary work
1. Disconnect the battery.
2. Remove front left wheel.
3. Remove front wheel housing liner at the left

Removing sub-part for front fan
1. Loosen sub-part for fan at all four fastening points -A- and release and pull off the plug connection.







2. Unscrew fastening nut -B- on ground point for front left longitudinal member and pull line off the threaded bolt.







INFORMATION: When cutting the front wire harness, make sure there is enough length of cable left to join to the new lines.

3. Cut the control line for the fan in area -x- (near the Medifuse box).







4. Remove tie-wrap at the Medifuse box in the front left wheel housing.
5. Release Medifuse box -A- from the bracket.







6. Open the cover of the Medifuse box at the six clips -A-.







7. Loosen fastening nut -B- on the B+ line and remove line from the Medifuse box.

Installing sub-part for front fan
1. Secure sub-part for fan at all four fastening points.
2. Fit ground strap at ground point for front left longitudinal member and tighten the fastening nut.
- Tightening torque: 9 Nm (6.5 ftlb.)

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 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 wire harnesses NR.155-2.

Crimping samples must be prepared before beginning work.

INFORMATION: Allocation of lines - see wiring diagram.

3. Crimp the control lines in area -x-.







3.1. Cut off lines in different lengths (due to the shrink-fit connections).
3.2. Slide shrink-fit hoses onto the lines.
3.3. Strip 10 mm of insulation off the wires.
3.4. Crimp lines using crimping sleeves and the hand crimping pliers from the repair kit for wire harnesses Nr.155-1.
3.5. Slide the shrink-fit hoses over the crimp connections and carefully shrink them using the hot-air blower with special nozzle (recommended accessories for repair kit for wire harnesses) so that they are watertight.
3.6. Wrap commercially available PVC tape all around the area of the connection points.
3.7. Secure the repaired area -x- to the main wire harness with tie-wraps.

4. Insert B+ line into the Medifuse box and tighten the fastening nut.
- Tightening torque: 9 Nm (6.5 ftlb.)

5. Close the Medifuse box and secure it at the holder in the left wheel housing.

Subsequent work
1. Install front wheel housing liner at the left.
2. Install front left wheel.
