The wheel differential & Axle differential wire is a specialized harness that enables the engagement of wheel and axle differential locks on the HOWO A7 8X4. This essential cable assembly, along with the Plastic fix belt ties, ensures secure routing and reliable electrical signals to the locking actuators. When you choose genuine howo Parts for your differential wiring, you guarantee consistent lock engagement, improved traction, and reduced driveline stress in demanding off-road and slippery conditions.
The Wire is a pre-assembled cable harness that carries control signals from the cab switch to the differential lock solenoids. It is specifically designed for the wheel differential and axle differential locking system of the HOWO A7 8X4.
This harness is built with high-quality copper conductors, insulated with cross-linked polyethylene to resist heat, oil, and abrasion. The connectors are sealed to prevent moisture ingress, ensuring reliable operation in wet and muddy conditions.
The cable length is optimized for the chassis layout of the 8X4, with enough slack to accommodate suspension travel. It is color-coded for easy installation, reducing the risk of miswiring that could damage the lock actuators.
For the wheel differential & Axle differential wire system, this harness is the critical link between the driver’s command and the mechanical locking mechanisms, providing the electrical pulse that engages the lock dogs.
Regular inspection of this wire is recommended, as chafing or cuts can lead to intermittent locking or complete failure, compromising the vehicle’s traction capability.
The Plastic fix belt is a heavy-duty cable tie used to secure the differential wiring harness along the chassis and axles. It is made of UV-stabilized nylon 6/6, providing excellent tensile strength and resistance to weathering.
These belts are 8mm wide and available in various lengths, ensuring a snug fit around the harness bundles. The self-locking head prevents loosening even under severe vibration.
For the wheel differential & Axle differential wire installation, these belts are used to attach the harness to the frame crossmembers, axle housings, and control arms, keeping the wiring away from moving parts and hot exhaust components.
Using genuine plastic fix belts ensures consistent clamping force and longevity, preventing the harness from sagging or chafing, which could lead to electrical shorts.
These belts are easy to install with a standard cable tie tool, and they can be cut flush to leave a clean appearance. A pack of six belts is supplied for a complete installation.

Our wheel differential & Axle differential wire harness is manufactured to the exact OEM specifications, ensuring perfect fit and function. The connectors are gold-plated for low resistance, and the insulation is rated for 125°C continuous operation.
The included Plastic fix belts are made from premium-grade nylon with UV inhibitors, ensuring they remain flexible and strong for years. This prevents the harness from drooping or rubbing against moving components.
Our harness is pre-tested for continuity and insulation resistance, so you can install it with confidence. The color-coded wires match the original wiring diagram, simplifying replacement and reducing errors.
We supply both the harness and the fix belts in one complete package, so you have everything needed for a professional installation. Choose our wheel differential & Axle differential wire solution for reliable traction control.
The wheel differential & Axle differential wire is the electrical pathway that activates the locking mechanisms for both the wheel differential (inter-axle) and the axle differential (cross-axle). These locks are crucial for maximizing traction in slippery or uneven terrain.
Without a properly functioning wiring harness, the lock solenoids may not engage, leaving the vehicle stuck in mud or snow. Even intermittent faults can cause dangerous lock engagement while driving, leading to driveline damage.
The harness is routed from the dash switch, through the frame, to the front and rear axles. It must be secured with fix belts at regular intervals to prevent chafing against the sharp edges of the chassis.
Over time, the original wiring can become brittle due to heat and oil exposure, causing cracks in the insulation and high resistance connections. Replacing with a new wheel differential & Axle differential wire restores reliable lock operation.
Before installation, disconnect the battery to avoid accidental short circuits. Remove the old harness carefully, noting the routing and attachment points for the wheel differential & Axle differential wire.
Lay the new harness along the same path, using the plastic fix belts to secure it to the frame every 250–300mm. Ensure the harness has enough slack to accommodate axle articulation but does not droop excessively.
Connect the harness to the lock solenoids and the cab switch, ensuring each connector clicks into place. Apply a small amount of dielectric grease to the terminals to prevent corrosion.
After installation, test the lock engagement by activating the switch with the engine running and listening for the solenoid click. Verify that the dashboard indicators light up correctly.
Always use new plastic fix belts for the installation, as old belts may have lost their tension and could allow the harness to move, causing chafing.
The wheel differential & Axle differential wire harness (A29725770082) is specifically designed for the HOWO A7 8X4 with the 80-length cable. It fits all variants equipped with both wheel and axle differential locks.
The Plastic fix belt (190003171697) is a universal component that can be used for any wiring harness in the truck, but it is included in this kit for convenience.
If your vehicle has a different length requirement, please contact our support team for alternative options. The harness is not interchangeable with other truck models without modification.
Always verify the part numbers against your vehicle’s VIN to ensure correct fitment. Using an incorrect harness can lead to improper lock engagement or electrical faults.
A reliable wheel differential & Axle differential wire ensures that the driver can engage differential locks instantly when needed, improving off-road capability and preventing the vehicle from becoming stuck in hazardous locations.
By using genuine parts, you avoid the risk of lock engagement failure, which could result in costly recovery and downtime. Our harness is built to withstand the harsh environment of construction and mining sites.
The plastic fix belts keep the harness organized and protected, reducing the likelihood of insulation damage that could cause short circuits and potential fire hazards.
For fleet operators, standardizing on this kit simplifies maintenance and ensures consistent performance across all vehicles. Regular inspection of the wiring and fix belts is recommended every 6 months.
We recommend using a multimeter to check the resistance of the harness during routine servicing – any increase beyond a few ohms indicates a developing fault that should be addressed.
Our technical support team is available to assist with any installation queries or to provide additional guidance on the wheel differential & Axle differential wire system. We are committed to keeping your HOWO A7 8X4 operating at its best.
