HOWO ABS/EBS Wiring Harness AZ9T2277001152 WG9X25770040

ABS/EBS wiring harness socket cable, part number AZ9T2277001152 – the same harness also appears as WG9X25770040 in the Sinotruk assembly list, so you will see both numbers quoted for this item. It fits Sinotruk HOWO TH7, HOWO TX, Sitrak and Hohan N7 heavy trucks. The harness links the ABS/EBS ECU to the wheel-speed sensor at the wheel end, so the braking system gets a clean, uninterrupted signal. We supply it as a direct OEM replacement: no cutting, no re-pinning, plug in and route it along the original path. Photo shows a batch of five; supplied per piece.

Specifications

Key Features

• Carries the AZ9T2277001152 marking on the tag and matches the WG9X25770040 line in the assembly list, so it cross-references from either number
• Tinned copper conductors hold a stable signal between the ABS/EBS ECU and the wheel-speed sensor, which is what keeps open-circuit and poor-contact warning lights off the dash
• Reinforced nylon connector shell with a sealed rubber gasket, IP67 rated against mud, rain, snow and road slurry
• Corrugated PA bellow outside the wire resists crushing and rubbing vibration on rough site roads
• Works from -40°C to +125°C, so the same part suits cold northern depots and hot tropical or high-altitude fleets
• Tinned pins resist salt-spray corrosion, which matters for coastal operators

Signs of Wear

Check the harness when an ABS or EBS warning appears together with a wheel-speed fault on one corner, or when the signal drops only on certain roads. Look for chafed conduit, a cracked or water-filled connector gasket, green corrosion on the pins and stretched wires at the wheel-end flex point. A damaged harness is far cheaper to replace than the ESC module and sensors it protects – and a bad signal from this run is one of the most common false ABS faults on Sinotruk trucks.
