Wire Harness Assembler

A wire harness assembler ties and routes wires for electrical equipment and systems. They may loop and link wires to various components manually or by using hand tools such as wire twisters, crimp presses, and wire strippers.

The responsibilities of a wire harness assembler include reading blueprints, wrapping wires at specified points to create a harness, and soldering wires to connectors. They determine harness specifications such as wire length and secure knots using sealing liquid. They protect the cables from moisture and other elements that may damage the wirings.

The efficiency of a wire harness assembler depends on their mechanical skills and knowledge. They must be capable to properly interpret wire diagrams and color codes to form the harness. They must observe and apply safety standards and policies to avoid hazards and accidents in the workplace.

What does a Wire Harness Assembler do?

Wire Harness Assembler

Wire harness assemblers are tasked with binding wires to form wire harnesses, which are typically used in electrical systems and electronic equipment. They read electrical wiring schemes and binds wires together using sleeves, cable lacing, cable ties, and electrical conduits. They are expected to install wire harnesses, inspect them, and perform soldering as needed.

As a wire harness assembler, you route and tie wires together to form wire harnesses, which are often referred to as cables. In this role, you may assemble and cut harnesses based on provided designs, install these harnesses in the designated locations, inspect components to ensure they are correct, and perform other tasks like soldering when necessary. 

You also repair damaged harnesses, including those located in hard-to-reach areas. This job title refers exclusively to creating cables and should not be confused with assembly jobs where you may wear a harness while working in elevated areas.

  • Detail Oriented

    Wire harness assemblers must interpret and follow cable-assembly instructions, schematics, and manufacturing drawings. They also read blueprints, specifications and work orders to determine materials, requirements, and assembly instructions.

  • Quality Assurance

    They must perform quality assurance checks and troubleshooting and debugging of all electrical systems on new machinery.

  • Communication Skills

    Wire harness assemblers must communicate with engineers and design staff to ensure consistency and troubleshoot any issues with designs or production.

  • Mechanical Knowledge

    These assemblers set up the machine that crimps the terminals onto bundles of wire by changing the spools of terminals using hand tools. To do this, they use of basic hand tools, cutters, wire strippers, soldering iron and heat gun.
