The first step of our business was in electrical wires.
Electrical wires—that connect electricity.
Where electricity is connected is where people lead their lives.
That means in towns and cities.
That means in communities.
Thus, what we have been connecting is our society itself.

This is why we have always demanded the best,
without compromise.

Though times will change and products will evolve,
our approach will remain unchanged.

We connect different parts within the vehicle.
These connections bring cars to life.
We connect the inside and the outside of the vehicle.
In creating connections, we create a better society.
Our commitment to this aim embodies what we are.

We give our word:
For greater safety, more convenience,and to be better to the environment.

With the best connections,
we will continue to create the best society.

Globally Uniform Designs Support
Rapid Development

Many electric vehicles are being equipped with high-powerdevices that act as a source of electromagnetic noise, which
can interfere in vehicles' communications. Meanwhile,
expansion of information networks both inside andoutside vehicles has also led to increasing use of precisioncommunication devices and electronics that are susceptible
to such noise. To deal with this, Sumitomo Wiring Systems
became the first Japanese harness manufacturer to set
up a chassis dynamometer test lab including an anechoic
chamber. We measure and evaluate the effects on parts
and the entire vehicle due to environmental changes insideand outside the vehicle, and utilize the results in developing
power supply and signal networks and related products.
In addition, our advanced research and evaluation facilities
and systems, including stringent durability tests and use of
CAE* in analyzing experimental data, helps ensure evengreater product reliability.

The SWS Group has created an environment that efficiently
provides the same quality with the same designs, no matter
which of our sites around the world the product is designed.
"HARBEST*" links parts information, manufacturing
instructions, cost calculations, and other manufacturingsystems. The "VAS*" development system reduces leadtimes with computer simulations from the initial design
stages to harness installation and manufacturing inspections.
"e-MACS*" is a tool for managing drawings and reports
and sharing design histories and other information.
With a design and development environment thatmakes full use of these andother original proprietarysystems, we are alreadycreating new value today.

Safeguarded by All Employees

The Pika-Pika Activity is an initiative based on thefundamental manufacturing principle that "Pika-Pika"(sparkling clean) thinking, actions, skills, equipment, andworksites lead to "Pika-Pika" products.
Initially, this was a movement calling for the "5S" efforts(Sorting, Setting-in-Order, Shining, Standardizing, andSustaining the discipline) in our plants, but now it is usedaround the world as a slogan in the aim of achieving"Globally Uniform Highest Quality."
At all of our global manufacturing sites, evaluators
dispatched from Japan join with onsite staff and work
together in performing the "PK evaluation," checking
and evaluating each production line, and clarifying areasof deficiency while accelerating improvements.

Wire harnesses consist of dozens or even hundreds ofwires and components, and since there are so many
types, they are made by hand. Regardless of their location
around the world, all of our employees receive the sameeducation and training needed to ensure "Globally
Uniform Highest Quality" and manufacture our products
in compliance with global standards.

Product Quality Further
Enhanced with Automated
Production Lines
We achieve Globally Uniform Highest Quality in the wires
and cables, connectors, and other parts that make up ourwiring harnesses by manufacturing these components
on highly automated production lines. We are promoting
more advanced production technologies and taking on thechallenge of improving quality with increased production
efficiency by incorporating IoT, robotics, AI, and other suchtechnologies, even at the wiring harness manufacturing stage.
