ABS Coiled Spiral Trailer Cable Assembly OE 3730040-T38H0 for Dongfeng KC Heavy Trucks

This genuine ABS coiled spiral cable assembly with OE number 3730040-T38H0 is original factory trailer electrical connection component exclusively designed for Dongfeng KC heavy-duty tractor-trailer ABS brake systems. It adopts high elastic wear-resistant PVC spiral cable with multi-strand pure copper inner conductors, matched with standard 7-pin fully sealed waterproof male and female ABS connectors. The retractable coil structure automatically stretches and retracts with trailer turning without wire pulling or breakage, maintaining stable ABS brake signal transmission. This spiral cable strictly passes DFCV OEM waterproof IP65 test, repeated stretch fatigue test and low temperature anti-brittle test. Authorized third-party auto electrical component inspection verifies pin definition, wire length and connector size fully consistent with factory original cables, widely used as replacement spare parts for cracked, aging or signal-loss ABS trailer wires on Dongfeng KC logistics tractors.

PRODUCT DESCRIPTION

Multi-strand oxygen-free pure copper inner conductor low-resistance signal transmission specification detail
01

Elastic Retractable Spiral PVC Wire, 7-Pin Fully Sealed Waterproof Connectors & Pure Copper Stable Signal

This OE 3730040-T38H0 ABS spiral cable uses high-toughness elastic PVC outer sheath, forming a retractable coil structure that freely stretches when the trailer turns and automatically rebounds without wire tangling or overstretching fracture. Internal multi-strand oxygen-free pure copper conductors deliver low-resistance, stable ABS brake signal transmission to avoid signal delay or failure during heavy load downhill braking. Both ends adopt standard 7-pin ABS fully sealed plastic plugs with built-in rubber sealing rings, reaching IP65 waterproof grade to block rain, mud and dust from entering pin terminals and causing short circuit. The plug buckle structure locks tightly after insertion to prevent accidental disconnection during bumpy road driving, perfectly matching Dongfeng KC original chassis and trailer ABS sockets without adapter modification.

Rigid Wire Breakage On Trailer Turning, Poor Waterproof Short Circuit, Unstable ABS Signal & Loose Plug Disconnection

Heavy truck fleet electricians and operators often face critical brake safety risks from inferior aftermarket ABS cables: non-coiled rigid wire pulls and snaps during trailer steering, cutting off ABS signal; low-grade un-sealed connectors let water seep into pins to trigger short circuit and ABS alarm; thin alloy conductors cause signal attenuation, leading to delayed trailer braking; simple plastic plugs loosen under vibration and fall off suddenly. This genuine DFCV OEM spiral cable completely eliminates these electrical system pain points: elastic coil avoids wire breakage; IP65 sealed plugs prevent water ingress; pure copper wires maintain steady ABS signal; locking buckle plug avoids accidental drop-off, reducing trailer brake failure accident risks.

DFCV OEM Trailer ABS Electrical Standard, Multi-Round Stretch & Weather Durability Lab Testing

As key safety signal transmission spare part of Dongfeng KC tractor-trailer ABS brake system, this spiral cable fully complies with Dongfeng Commercial Vehicle official automotive electrical production quality standards. Every finished ABS coil cable completes three mandatory professional durability laboratory tests: 10,000-cycle repeated stretch rebound fatigue test, IP65 high-pressure water spray waterproof test, -40℃ low temperature PVC anti-brittle cracking test, maintaining stable electrical performance under cold northern winters, rainy coastal transportation and bumpy construction site road conditions. Each cable is attached with official OE label for genuine product traceability, all plug pin layout, coil stretch length and wire resistance strictly match original vehicle factory technical drawings, zero pin mismatch after replacement.
