Electrical Assembly & Wire Harnessing

Electrical Assembly & Wire Harnessing

Electrical Assembly Built for Real Production Environments

Reliable wire harnesses, control boxes, and electromechanical assemblies built with documented process control, trained operators, and 100% testing.

Electrical assemblies create problems when the process behind them is inconsistent. RELY moves electrical assembly and wire harnessing work into a controlled, repeatable process — install-ready, documented, tested, and built to perform.

IPC/WHMA-A-620 Aligned 100% Continuity Tested ISO 9001:2015 Certified Prototype to Production
Where RELY Fits

Electrical Assembly That Takes Pressure Off Your Operation

Manufacturers often struggle to keep electrical assembly work stable when demand shifts, documentation is limited, or skilled internal labor is already stretched. RELY gives you a controlled outside production path for electrical assembly work that needs consistency, flexibility, and accountability.

We are a strong fit when the work is too labor-intensive, too high-mix, too inconsistent, or too disruptive to keep inside your core production flow.

RELY Supports
  • Custom Wire Harnesses
  • Power, Signal & Data Harnesses
  • Control Boxes & Panels
  • Electromechanical Modules
  • DIN Rail & Terminal Block Assemblies
  • Prototype, Pilot, Production & Service-Part Builds
Wire Harnessing

Built for Routing, Continuity, and Repeatability

RELY builds wire harnesses from simple jumpers to complex multi-circuit assemblies. Every harness is built to reduce misrouting, prevent stress points, support clean installation, and eliminate avoidable troubleshooting. Every harness is also 100% continuity tested before it leaves our facility.

Wire Gauge Range 8 to 22 gauge
Insulation Options PVC, silicone, TPE, GXL, TXL, and application-specific options
Connector Support Bosch, Delphi/Aptiv, Deutsch, Molex, TE/AMP, and other common platforms
Build Method Custom build boards with defined routing and wire dressing standards
Identification Labeling and circuit identification per customer spec
Protection Strain relief and abrasion protection where required
Verification 100% continuity testing on every harness, every time
Control Boxes & Modules

Install-Ready Electrical Assemblies

Control boxes and electromechanical assemblies need to arrive ready to install, not ready to diagnose. RELY builds these assemblies with consistent layouts, defined wire paths, secure connections, and clear labeling so your team is not troubleshooting wiring differences from one unit to the next.

Common Assemblies
  • Breakers
  • Power Supplies
  • Relays
  • Sensors
  • Terminal Blocks
  • DIN Rail Components
  • Control Hardware
  • Mounted or Enclosed Electromechanical Components
Process Controls
  • Standardized Component Placement
  • Defined Wire Routing
  • Verified Torque Where Required
  • Secure Terminations & Connections
  • Clear Circuit Identification
  • Visual Inspection vs. Workmanship Standards
  • Final Electrical Verification
Testing & Traceability

Verification Built Into the Process

Testing is built into the process, not treated as a final catch-all. RELY uses controlled inspection and testing steps to catch issues before they move downstream into your facility, your customer’s operation, or the field.

Built to Scale With Your Program

Electrical programs change over time. Demand increases, revisions happen, legacy products stay active, and service demand continues long after the original launch. As volume grows, RELY scales through trained operators, structured build cells, documented work instructions, and repeatable production methods.

Why It Matters

Scale Electrical Assembly Without Disruption

RELY gives manufacturers a controlled way to scale electrical assembly and wire harnessing without adding permanent labor, pulling skilled people away from core production, or accepting inconsistent quality.

Without RELY

Absorbing It Internally

  • x Complex builds consume engineering and technical production capacity
  • x Product variation and revision changes increase execution risk
  • x Skilled teams get pulled into assembly, troubleshooting, and rework
  • x Material coordination and long BOMs create operational strain
  • x Build inconsistencies create downstream startup, service, and quality issues
With RELY

Freeing Up Technical Team Capacity

  • Complex harness and control panel builds are managed by a disciplined external team
  • Internal engineering and production teams stay focused on higher-value priorities
  • Structured assembly processes improve consistency across builds and revisions
  • Material coordination and execution support reduce operational drag
  • Earlier issue detection helps reduce rework, startup delays, and downstream risk

Let’s Talk

Need More Electrical Assembly Capacity?

If your team is dealing with inconsistent electrical builds, labor constraints, install issues, or scaling challenges, we should talk. We’ll help you identify where time, quality, or capacity is being lost and show you where RELY can take pressure off your operation.
