Wiring Harness Navigation / Compact Point Guide / Wiring Harness Assembly Aid

Futura's line of Harness Assembly Aid products are used for sub assembly process guidance eventually resulting in reduced errors and faster assembly time.

harness assembly aid

Futura's Harness Assembly Aid solutions provide intelligent, step-by-step process guidance at the point of assembly — systematically reducing build errors, accelerating cycle times, and driving measurable improvements in throughput.

Fully autonomous operation

Deploys as a self-contained system requiring no external software, servers, or integration overhead — enabling fast commissioning directly on the shop floor with minimal IT involvement.

Error-proof assembly guidance

Guides operators through each assembly step with visual cues and real-time verification, catching mistakes before they propagate and significantly lowering defect and rework rates.

Built for industrial-grade reliability

Engineered to perform consistently in demanding production environments, with ruggedised hardware, long service life, and dedicated technical support to keep operations running without interruption.

Harness navigation: poka-yoke wire harness assembly

In wire harness assembly, operators insert crimped wires into connector housings by hand. With dozens of cavities per connector, a single wire in the wrong cavity or a terminal that is not fully locked can slip through to the customer.

A harness assembly aid, also called a harness navigation system, is a poka-yoke (error-proofing) device that guides the operator through the assembly of the harness step by step. It lights an LED under the correct cavity for each wire, so the operator always knows where the next wire goes. It checks continuity and insertion location as the harness is built, and detects terminal backout (TBO) with a pull check. New operators reach full speed quickly because the system does the remembering for them.

Which harness navigation system fits your line

  • HACT 121: stand-alone continuity tester that finds shorts and open terminals and guides wires into empty couplers with LEDs.
  • HAFX: non-programmable assembly aid for fixed points, with continuity, insertion location and TBO checks.
  • HAAP: harness assembly aid with pull navigation for step-by-step guided assembly.
  • HAAP TS: touch screen, PC based harness navigation with user authentication.

Frequently asked questions

What is wire harness assembly?

Wire harness assembly is the process of cutting and crimping wires, inserting the terminals into connector housings and binding the wires into a harness that carries power and signals through a vehicle or machine. Assembly aids guide the insertion step, which is where most errors happen.

What is harness navigation?

Harness navigation is another name for a harness assembly aid. The system navigates the operator through each assembly step with LEDs and checks every wire as it goes in, so the harness is built right the first time.

How does an assembly aid make harness assembly poka-yoke?

Poka-yoke means designing a process so mistakes cannot pass unnoticed. The assembly aid only shows the correct cavity for each wire and checks continuity, insertion location and terminal backout immediately, so a wrong or loose wire is caught at the station instead of at final test.

What is the difference between an assembly aid and a harness tester?

An assembly aid guides the operator while the harness is being built and checks each wire as it goes in. A harness tester checks the finished harness at the end of the line. Many plants use both.

Does an assembly aid need a PC?

No. HACT 121 and HAFX are stand-alone units. HAAP TS is PC based and adds a touch screen with step-by-step navigation.
