Premium Sinotruk HOWO Electrical System Parts Wholesale
Modern heavy-duty trucks rely heavily on advanced electronic controls to maintain peak engine efficiency, vehicle tracking, and driver safety. The electrical system acts as the "nervous system" of your vehicle. A single faulty sensor or a corroded wire harness can stall an entire logistics operation. As a leading exporter of heavy truck spare parts, we offer a comprehensive stock of high-performance HOWO electrical system parts to keep your fleet running smoothly without unexpected electrical failures.
All our electrical components are manufactured to meet or exceed strict 24V original truck standards. Whether you need a powerful starter motor for cold-weather ignition, a reliable alternator, or high-precision engine ECU controllers, we provide 100% Genuine original parts and premium OEM replacements compatible with HOWO 7, HOWO A7, and T7H/TX heavy trucks.
Key Electrical Components We Supply:
- Starting & Charging Systems: Heavy-duty 24V starters (e.g., 7.5KW/11T), high-output alternators, and durable battery switches.
- Sensors & Switches: O2 sensors, oil pressure sensors, coolant temperature sensors, ABS wheel speed sensors, and universal combination steering switches.
- Electronic Control Units (ECUs): Engine control modules, CBCU (Central Body Control Units), and instrument clusters for accurate diagnostics.
- Wiring & Lighting Control: Flame-retardant complete cabin wiring harnesses, chassis cable assemblies, relay boxes, and heavy truck fuse blocks.
Why Choose Our Electrical Parts?
| Feature | Our Advantages | Customer Benefits |

Frequently Asked Questions (FAQ)
Q1: Are your HOWO electrical parts designed for 12V or 24V electrical systems?
A: All standard Sinotruk HOWO heavy trucks operate on a 24V electrical architecture. All components under this category, including starters, alternators, relays, bulbs, and control modules, are strictly rated for 24V commercial vehicle systems unless specified otherwise for light-duty models.
Q2: What should I provide if I need to purchase a replacement ECU or CBCU controller?
A: Because electronic control units are deeply integrated with specific engine models and emission standards (Euro II, III, IV, or V), we strongly request the original part label photo, the exact engine model number (e.g., WD615.47), or the truck's VIN number. This allows us to ensure the module is flashed with the correct hardware firmware for your specific market.
Q3: How do you protect sensitive electronic parts like sensors and ECUs during shipping?
A: Electronic parts are highly sensitive to moisture and physical shocks. We package all ECUs, sensors, and instruments using anti-static bubble wrap pouches, then place them into durable individual boxes filled with shock-absorbing foam inserts. For sea shipping, these boxes are sealed in moisture-proof outer plastic linings inside reinforced export cartons.
Q4: Do you accept mixed orders of different switches and sensors for small inventory replenishment?
A: Yes, we do! We specialize in supporting B2B wholesalers and fleet maintenance centers. For standard universal items like switches, relays, and sensors, we have flexible MOQ policies, allowing you to combine hundreds of different small electrical parts into a single consolidated cargo box or pallet shipment to minimize freight costs.
