Position a wire to the corresponding connection point on the jack.
Carefully apply a small amount of solder to hold the wire in place.
Repeat this for each wire.
Make sure to reference the mapping of wires to connection points that you created in Step 4.
When soldering the wires, be patient and meticulous about getting the right position to make a good connection.
If the internal wires do not have their own insulation, use a small bit of shrink tubing on each wire. This will prevent them from shorting across another wire.

将一根线缆放置到插孔对应的连接点上。
仔细地涂上少量焊锡使线缆固定。
对每根线缆重复这项操作。
请务必参考您在步骤4中记录的连线点映射图。
焊接电线时，要耐心细致地找到合适的位置，以便连接良好。
如果内部线缆没有了绝缘层，在每根线缆上使用一些收缩管。这样可以防止他们与另一根线缆短路。
