Full Electronic Equipment Box Build with Custom Wiring

Cable and Wire Harness Assembly

Reliable, Custom Assemblies Built to Your Requirements

Cable and wire harness assemblies organize, protect, and route electrical wiring and cables in a durable, compact form. By bundling wires together with protective sheathing, connectors, strain reliefs, and labels, you simplify installation, reduce wiring errors, and make servicing easier. Well-built harnesses also protect against abrasion and environmental damage while enhancing product performance, safety, and reliability.

Cable and Wire Harness Assembly Services

TASC helps streamline installation, reduce production time, and improve system reliability with expertly assembled, thoroughly tested cable and wire harnesses. Whether you need a one-off prototype or a production-ready harness for a complex system, we tailor every solution to your technical and scheduling needs. Our deep experience, modern tooling, and industry certifications ensure every assembly is ready to perform—right out of the box.

Custom Design and Prototyping

Accelerate development with design-to-spec and reverse engineering support. Whether starting from scratch or working from a sample, we help you reduce development time and ensure your harness meets performance and compliance requirements.

Precision Termination and Soldering for Long-Term Reliability

We’ve invested heavily in state-of-the-art wire cutting, stripping, crimping, and soldering tools to deliver clean, consistent terminations that stand up to electrical and mechanical stress. Our processes support a wide range of wire gauges, connector types, and production volumes.

Connector and Terminal Installation

Avoid costly connection issues with professionally installed components from trusted Tier One manufacturers. Our experienced technicians ensure secure fit, proper mating, and long-term reliability.

Protective Potting for Harsh Environments

For assemblies exposed to vibration, moisture, or contamination, potting adds a tough, moisture-resistant barrier that protects wire-to-contact connectivity and extends service life.

Clear Labeling and Full Traceability

Color-coded wires, barcoding, and documentation make installation and servicing faster and easier while supporting traceability and compliance with your documentation standards.

Thorough Testing

Every assembly undergoes continuity testing, insulation resistance testing, pull testing, and visual inspection to verify performance before it leaves our facility—minimizing the risk of field failures.
