Dongfeng GX truck parts instrument panel B Wire harness protection panel 5305156-C6200

Built as the first line of defense for instrument panel B area wire harnesses, this protection panel features a multi-dimensional protective design. The main body is made of impact-resistant PP+ABS composite (UL94 V-0 flame-retardant grade) with a 3mm thickness, capable of withstanding 30J impact energy—shielding harnesses from accidental tool collisions or cargo bumps. The inner surface is lined with 5mm-thick EPDM foam, which cushions vibration (10-500Hz) from the truck’s chassis and prevents metal-to-wire abrasion. The enclosed structure achieves IP54 protection, blocking dust, water splashes from cleaning, and oil mist from the engine bay—reducing short circuit risks by 70%. It also resists UV radiation, avoiding harness insulation aging caused by sunlight penetration

Engineered to optimize wire harness management in the crowded instrument panel B area, the 5305156-C6200 panel integrates dedicated routing features. It includes 6 pre-formed, size-classified grooves (15mm, 20mm, 25mm width) that separate power harnesses (e.g., instrument cluster, airbag) from signal harnesses (e.g., GPS, multimedia)—avoiding electromagnetic interference (EMI) that causes system malfunctions. Each groove is equipped with built-in nylon cable ties for secure fixation, preventing harness movement during vehicle operation. Embossed labels (e.g., “Instrument,” “Airbag,” “Audio”) on the panel surface enable quick harness identification, reducing diagnostic and maintenance time by 50%. A removable inspection flap (secured by snap clips) provides easy access to connection points without disassembling the entire panel

Optimized for long-term reliability and driver comfort, the protection panel adopts high-performance materials and human-centric design. The PP+ABS composite undergoes scratch-resistant treatment (pencil hardness ≥2H), withstanding scuffs from cleaning tools or accidental contact without visible damage. The edges are rounded (R6mm) to prevent scratches on technicians’ hands during maintenance and avoid snagging on clothing. The panel’s surface features a matte texture that matches the instrument panel’s finish, ensuring visual consistency and reducing glare. It operates stably in extreme temperatures from -40℃ to 85℃, avoiding brittleness in cold weather or deformation in sun-exposed cabs. The EPDM foam is anti-mildew, preventing odor buildup in humid environments

This instrument panel B wire harness protection panel is designed for efficient installation and long-term cost savings for Dongfeng GX operators. The pre-assembled structure (main panel + foam lining + cable ties + mounting hardware) allows a single technician to complete replacement in 45 minutes using only a screwdriver and socket wrench—no adhesive, cutting, or specialized tools required. The OE-compatible design eliminates gaps between the panel and instrument panel, avoiding rattling noise or harness pinching issues common with aftermarket panels (repair costs up to $600). By protecting harnesses from damage, it extends their service life to ≥600,000km—twice that of unprotected harnesses—reducing replacement frequency. Backed by a 2-year/300,000km Dongfeng warranty, it provides reliable electrical system protection and predictable maintenance expenses for fleet operations
