1: the ambient temperature of the engine is high, and there are more corrosive gases and liquids. Therefore, the wire of the engine wiring harness must use wire resistant to high temperature, oil, vibration and friction.
2: the wire on the automatic transmission is resistant to hydraulic oil, high temperature resistance and good temperature stability.
3: The wire harness on the trunk cover should keep its elasticity at low temperature, so cold elastic wire should be selected to ensure its normal work.
4: weak signal sensor to use shielded wire, such as detonation sensor and crankshaft position sensor, ABS wheel speed sensor, medical equipment wiring harness, etc..
5:ABS wire harness assembly used 150-200℃ high temperature resistance, outer protective insulation layer hard, wear-resistant, but the wire core should be greater than 133 stranded wire.

6: power line such as starter ac generator output line battery line used for the wire can withstand high current insulation layer heat dissipation performance, voltage reduction special wire.
