Automotive wiring harness from a functional up points, carrying the drive actuator (actuator) electricity power lines and transmission of sensor input command signal line two. Transporting coarse wire power line is a large current, and the signal line is not carrying power of thin wire (optical fiber communications); e.g., wire cross-sectional area of ??the signal circuit is 0.3,0.5mm2. Common specifications common wire harness inside the car have a nominal cross-sectional area of ??the wire 0.5,0.75,1.0,1.5,2.0,2.5,4.0,6.0 such as square millimeters (commonly used in cars nominal cross-sectional area of ??0.5,0.85,1.25, 2.0,2.5,4.0,6.0 mm, etc.), each of which has a permissible load current value, with different power wires for electrical equipment. To the vehicle wiring harness, for example, 0.5 specification line is suitable for instrument lights, lights, door lights, ceiling lights, etc; 0.75 specification line applies to the sale of sophisticated license plate light harness, front and rear small lights, brake lights, etc; 1.0 specification applies to the steering lines lights, fog lamps; 1.5 specification line is suitable for headlights, horn, etc; the main power line such as a generator armature wire, grounding lines, and require 2.5 to 4 mm2 wires. This refers only to the general terms of precision automotive wiring harness tester, the key depends on the maximum load current value precision harness manufacturers, such as battery grounding line, the positive power line is dedicated automotive wire alone, their diameter are more large, at least a dozen square millimeters or more, these "giant" in the White wire harness will not compile.
