Our Capabilities

We combine collaboration with our customers, design expertise, custom engineering, and quality manufacturing to produce harnesses for vehicles, industrial equipment and specialty products.

Product Realization Process

As a Tier 1 and Tier 2 leading manufacturer for the automotive industry, the GSW team uses a proprietary Product Realization Process that incorporates both Advanced Product Quality Planning (APQP) and our own Quality Assurance (QA) system to meet the needs of our customers.
With quality embedded in every step, this system ensures our customers have a smooth, collaborative experience from design through delivery. Our expertise at every stage of the process enables us to provide our customers flexibility to choose only a few steps or the entire process. Each step provides distinct value. For example, our build to print capabilities enable us to shorten lead times to expedite the production and delivery of products.
Our method also provides our customers with detailed documentation including:
  • Production Part Approval Process (PPAP)
  • Failure Mode Effects Analysis (FMEA)
  • Control Plan (CP)
  • Measurement System Analysis (MSA)


From the first conversation with a customer, our solutions orientation empowers us to bring our customer’s idea to reality. Our design process includes seven key elements:

We conduct thorough conversations to explore your application and need


We leverage our expertise and knowledge to offer options for enhancements and a suite of solutions


Together we determine the best solution and then use Catia and AutoCad Inventor to help you visualize our design enhancements and recommendation


We manufacture a single piece to assess, modify if necessary, and prepare for mass production


We can manufacture a quality product in a wide range of volumes


We can review current products to identify opportunities for improvement


We use VAVE (value added/ value engineered) to provide enhancements

Our affiliation with G.S. ELECTECH in Japan, also provides us exclusive access to extend our resources for the design and development of new parts for OEMs and Tier 1 manufacturers.

Innovation & Technology

At GSW we partner with our customers to design wire harnesses and optimize processes that meet their future needs. We leverage our in-house talents and expertise to ensure our designs are cutting edge. We utilize state-of-the-art materials and develop processes that provide robust quality and productivity. Jointly our specialized departments are applying leading technologies to develop process automation.

Data-driven Approach

With more than 30 years of amassed knowledge, our data-driven approach is a strategic differentiator from our competitors. We apply this approach to our decision making, strategic planning and consultative approach with our customers. The benefits range from improved quality, increased performance, cost reduction to supply chain optimization.
Ensure Quality

We can predict and identify potential quality concerns and root causes long before products leave our facilities.

Optimize Resources

Our business intelligence strategy allows our team members to gain insights more efficiently to add value and identify obstacles before they become unneeded costs.

Increase Performance

With the use of cutting-edge technology, we consistently automate non-value-added activities throughout our organization.

Optimize Supply Chains

We capably and proficiently identify profitable opportunities despite the complex data associated with an international supply chain.


GSW maintains certifications in ISO/IATF 16949, ISO 14001 and C-TPAT to ensure quality in our processes and products that exceeds the expectations of our customers.
