Durable Wiring: Uses color-coded, high-strand copper wire with insulation resistant to heat, oil, abrasion, and chemicals commonly found in a harsh equipment environment.
Molded Connectors: Features robust, sealed connectors (often with Deutsch or CAT-specific designs) that are waterproof and dustproof (meeting IP67 or similar ratings). This prevents corrosion and ensures reliable connections despite vibration and moisture.
Precision Terminals: Gold or tin-plated terminals minimize resistance and prevent oxidation.
This 306-8504 cab wiring harness is used for 336D2 C9 336D2GC 340D2 excavator.
