7. Qualities of Automotive Wire
As a backbone of the signal transmission in vehicles, a check on the quality is too essential. Modern technology has a significant focus on digitization. The wiring harness needs to be durable. It needs resistance to heat, humidity, vibration, temperature fluctuations, and external mechanical shocks.
Choose the material with the best durability and resistance. It can help to tap the maximum potential from the wiring harness. It should withstand high temperatures, excessive and unwanted vibrations.
8. Tests for Automotive Wire
It is not just before the launch of a rocket that scientists order &#;Check.&#; The wiring harness of automobiles needs special tests to ensure smooth service. Todays&#; manufacturer uses fast and advanced testers, and they perform accurate and high- speed tests on the wiring harness. They can achieve continuity, weight, vibration, and design check tests in a span of a few seconds.
The test of continuity ensures that it is not an open circuit. The test will show a positive result if all the connectors are functioning correctly. Proper testers import and export accurate data and display appropriate results.
9. Look for Customization Manufacturer
Your project needs to depend on a manufacturer who understands your business needs. Since every automotive business is different, you need someone who can help you get custom wiring harness, while ensuring you meet the legal requirements. Look at whether your wiring harness manufacturer can customize to your requirements, and the features they offer.
10. Automotive Wire Harness for Alternate Energy Sources
The conventional sources of energy are on the decline. A point of no return is sure to await us in the future when there is not any more fossil fuel left. Do not let time stand still then.
Automotive wiring harness does not limit itself to a narrow spectrum. Rather, you can use it in all vehicles that derive energy from alternate sources. These include LPG, natural gas, fuel, and even electric and hybrid vehicles.
You need to adapt to change. Nurture a technology like automotive wiring harness. It&#;s going to serve both future and existing conventional models.

The wiring harness is the main body of the network of automotive circuits, and without the harness, there would be no automotive circuits. At present, whether it is a senior luxury car or an economical ordinary car, the form of the automotive wiring harness is basically the same, which is composed of wires, connectors, and wrapping tape.
Automotive wire, also known as low-voltage wire, wire are copper multi-core flexible wire common specifications are 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0 square millimeters, each with the allowable load current value.
Take the whole vehicle wiring harness as an example:
0.5 gauge wire for instrument lights, indicators, door lights, dome lights, etc.; 0.75 gauge wire for license plate lights, front and rear lights, brake lights, etc.; 1.0 gauge wire for turn signals, fog lights, etc;
1.5 gauge wire is suitable for headlights, horns, etc;
The main power cord requires 2.5 to 4 square millimeter wire. The key is to look at the maximum current value of the load, such as the battery override cable, positive power line is a special car wire used separately, their wire diameter of more than ten square millimeters.
The main wiring harness is generally divided into the engine (ignition, EFI, power generation, starter), instrumentation, lighting, air conditioning, auxiliary appliances, and other parts, with the main wiring harness and branch wiring harness.
The main wiring harness of the whole car often takes the instrument panel as the core part and extends before and after. It is divided into front wiring harness (including instrumentation, engine, front light assembly, air conditioning, battery), rear wiring harness (tail light assembly, license plate light, luggage compartment light), roof wiring harness (door, roof light, audio speaker), etc.
The most basic automotive wiring harness will typically contain 12 "circuits", or lengths of wire for a specific purpose, with a designated fuse holder in the fuse block for each circuit:
Radio
Wipers
Turn Signals
Gauges
Stop Lights
Horn
Hazard Flasher
Taillights
Parking Lights
Dash Lights
Distributor
Heat & A/C
Each of the circuits listed serves a vital or extremely common electrical accessory, which is why most wiring harnesses come with at least 12 circuits. However, many vehicles have additional electrical accessories beyond those listed. An 18 circuit harness may add six circuits for power accessories, such as:
Power Windows
Power Locks
Electric Fan
Electric Fuel Pump
High Level Stop Light
Radio B+ Memory
And a 24 circuit harness will add wiring to support additional accessories:
Under Hood Light
Clock
Lighter
Dome Light
Trunk Light
Glove Box Light
As you can see, the number of circuits you need for your wiring harness will depend on the electrical accessories you have (or want to have) in your vehicle
Wire harnesses on the ends of the symbols on the numbers and letters to mark the connection of the wire object, the operator can see the symbols correctly connected to the corresponding wires and electrical devices, to facilitate the repair or replacement of the harness; or the same circuit with a wire color to distinguish
The color of the wire is divided into single-color wire and two-color wire, the use of color is generally the standard set by the car factory.
The surface of the wire harness is wrapped in different ways according to the different parts of its use:
Engine harnesses work in a harsh environment, so they are all wrapped with high flame retardant, waterproof, and high mechanical strength threaded pipe.
The working environment of the front cabin wire is also relatively poor, most of the branches are also wrapped with threaded pipe with good flame retardancy, and some branches are wrapped with PVC pipe.
Instrument line working space is small, the environment is relatively good, available tape full wrap or flower wrap.
The door line and headliner line workspace is small, available tape full wrap, part of the branches available industrial plastic wrap; finer headliner line can be directly glued to the body with sponge tape.
Chassis line because of more contact parts with the car body, so the bellows wrap to prevent the harness wear damage.
