Positions of Fleece Tape for Automotive Wiring Harness

Main application positions inside the vehicle

1. Instrument panel wiring harness

    

   Inside the instrument panel, there are numerous complex wiring harnesses. Fleece tape is widely wrapped on main harnesses and branch harnesses to avoid abnormal noise from vibration‑induced friction between harnesses and plastic housings.
2. Door wiring harness (four doors)

    

   Wiring harnesses behind door trim panels, for door panels and window lift motors. It eliminates rustling abnormal noise caused by friction between wiring harnesses and plastic door panels.
3. Seat wiring harness

    

   Wiring harnesses under and inside seat backs (for seat motors, heating and ventilation systems). Seats move and vibrate frequently; fleece tape provides cushioning, noise reduction and wear resistance.
4. Roof wiring harness

    

   Wiring harnesses under the headliner (for sunroofs, reading lights and ambient lights). Limited roof space prevents knocking‑induced abnormal noise of wiring harnesses.
5. A/B/C‑pillar wiring harness & floor wiring harness

    

   Wiring routed inside body pillars and beneath interior floor trims. Harnesses close to sheet metal and plastic parts are wrapped partially with fleece tape for cushioning and noise suppression against vibration impacts.
6. Harness branches, corners and connector roots

    

   Bends, split points and connector sheath positions are prone to abnormal noise from hard‑soft contact. Local fleece‑tape wrapping provides cushioning and vibration damping.

    

Areas rarely or never used

• Engine compartment: High‑temperature and oily environment. Fleece material absorbs oil easily. High‑temperature‑resistant PVC or polyester fabric tape is normally adopted. Only a small amount may be used locally near the firewall at low‑temperature zones.
• Chassis and wheel arch / exterior wiring harness: Exposed to mud and water splash. PVC corrugated tubes and PVC tape are preferred instead of fleece tape.
