The biggest difference between Automotive Wiring Harness standards in various countries is that apart from their different testing, the biggest difference is that Wiring Harness of the same specification has different structure, cross-sectional area, material usage classification, wire insulation thickness and material ratio.Different car manufacturers will choose different Automotive Wiring Harness standards.Automotive Wiring Harness low-voltage wires mainly have the following standards: German standard, Japanese standard, Korean standard, American standard and national standard, etc. The specific performance and standards are compiled by Dongguan Jiuwang Electronics, a professional manufacturer of Automotive Wiring Harness.
