FAQ
Q1: What is an automotive wire harness?
A1: An automotive wire harness is a bundled assembly of wires, terminals, and connectors that transmits electrical power (for engines, batteries) and signals (for infotainment, sensors) throughout a vehicle, organizing wiring to save space and improve reliability.
Q2: Can China 365PCB manufacture harnesses for electric vehicles?
A2: Yes, we specialize in EV wire harnesses, including high-voltage battery cables, charging system wiring, and thermal management connections—all tested for high-voltage safety and thermal resistance to meet EV-specific requirements.
Q3: Do you provide waterproof automotive wire harnesses?
A3: Yes, we offer IP67/IP68-rated waterproof harnesses, ideal for exposed areas like engine compartments, underbodies, or off-road vehicles—protecting against moisture, dust, and debris.
Q4: What quality standards do your automotive harnesses meet?
A4: All harnesses comply with IPC/WHMA-A-620 (wire harness assembly standards) and can meet additional automotive-specific standards like ISO/TS 16949 (quality management), OEM-specific requirements, and RoHS (environmental compliance).
Q5: What is the lead time for a custom automotive harness order?
A5: Standard production lead time for custom automotive harnesses is 10–15 business days. For urgent orders (e.g., OEM production gaps), we offer expedited manufacturing to meet tight deadlines.
