Custom Wire Harness Design & Engineering
Engineering expertise needed to turn your requirements into a rapid wire harness solution.
Custom Wire Harness Engineering from Concept to Product
Whether you’re developing a new electrical system, improving an existing design, or working from an early-stage concept, RFA Engineering provides the engineering expertise needed to turn your requirements into a rapid wire harness solution.
Our engineers work alongside your team to understand technical requirements, packaging constraints, operating conditions, component needs, and production goals. We can work from existing drawings and CAD models or help develop a solution when the design is still taking shape.
Engineering Support Built Around Your Project
RFA’s capabilities extend beyond simply manufacturing a supplied design. Our engineering team can support:
- Wire harness and cable assembly design
- CAD modeling and 2D drafting
- Engineering drawings for PLM requirements
- Component and connector selection
- Reverse engineering and schematic probing
- Solution development
- Power distribution and panel design
- Electromechanical sub-assemblies
- Design refinement for manufacturability
Our team can work with customer-supplied drawings, concepts, models, or existing designs, providing the level of engineering support your project requires.


Component & Material Expertise
Selecting the right components is an important part of developing a reliable harness. RFA works with a broad range of connector families, wire sizes, communication systems, and protective materials, including Deutsch, Molex, Tyco, AMP, Aptiv, J1939 CAN bus, coax, loom, conduit, sleeving, and braiding.
From Engineering to a Physical Build
Because engineering and manufacturing capabilities are available within the same team, designs can move efficiently from development into prototype and small-batch production. This helps connect design decisions with real-world manufacturability rather than treating engineering and fabrication as separate activities.

Still Shaping Your Harness Design?
Our engineers are ready to review your requirements and turn drawings, models, or early concepts into a buildable harness solution.
