EA211 wiring harness has oil how to clean up

How to clean up EA211 wiring harness with motor oil

Use a paper towel and vinegar, wipe for 5 minutes, the oxidization on the plugs will also fall off, and to the plugs will likewise be somewhat flowery.

Oxalic acid (i.e., glycolic acid) can be used to remove rust. Be careful when using it though, oxalic acid is highly corrosive to stainless steel. High concentrations of oxalic acid also tend to corrode hands. And generated acid oxalate solubility is great, but there is a certain degree of toxicity. When using, just don't eat or drink it. After skin contact with oxalic acid, it should be washed with water in time.

Automobile wires, also known as low-voltage wires, are different from ordinary household wires. Ordinary household wires are copper single-piston wires, with a certain degree of hardness. And car wires are copper multi-pistil wire, some soft wire as thin as a hair, several or even dozens of soft copper wire wrapped in plastic insulation tube (PVC), soft and not easy to break.

Automotive wiring harnesses due to the specificity of the automotive industry, the manufacturing process of automotive wiring harnesses is more special than other common wiring harnesses.

The system of manufacturing automotive wiring harnesses is broadly divided into two categories:

1. Divided by Europe and the United States, including China:

Use the TS16949 system to control the manufacturing process.

2. Japan-based:

such as Toyota, Honda they have their own system to control the manufacturing process.

With the increase of automobile functions and the common application of electronic control technology, there are more and more electrical parts, the wires will be more and more, and the wiring harness will become thicker and heavier. Therefore advanced automobiles have introduced CAN bus configurations that utilize a multiplexed transmission system. Compared with the traditional wiring harness, the multiplexing device greatly reduces the number of wires and connecting plug-ins, making the wiring easier.
