Automotive wiring harness plug is an indispensable part of automotive electrical system, it is connected to various electrical equipment and sensors, and plays the role of transmitting electrical signals. However, in the process of use, sometimes the plug needle will fall off, at which time it is necessary to withdraw the needle. Below, we will introduce how to withdraw the needle of the car wiring harness plug.

First, we need to prepare some tools, including needle withdrawal tools, tweezers, scissors and so on. A needle withdrawal tool is a tool specifically designed for needle withdrawal, which has a small hole in the head to hold the plug pin and then gently pull it out. Tweezers and scissors are tools used to assist in operation.

If the plug needle is relatively tight and can not be pulled out, you can use scissors to cut the two sides of the plug needle slightly, and then use the needle withdrawal tool to pull out. However, the use of scissors should be very careful, so as not to cut the harness or plug.

After the withdrawal is complete, we need to check the plug and harness for damage. If any damage is found, it needs to be replaced or repaired in time. At the same time, we also need to pay attention to the number and location of the plug pin, so as to avoid misinsertion or missing insertion.

In short, the withdrawal operation of the car harness plug needs to be careful to avoid damaging the plug or harness. In the operation process, we need to prepare the corresponding tools, gently pull out the plug pin. After the withdrawal of the needle is completed, it is also necessary to check the plug and wiring harness for damage to ensure the normal operation of the car's electrical system.
