Onlink is a custom automotive wiring harness manufacturer providing complete wiring assemblies for automotive electrical systems, industrial control equipment and customized electromechanical products.
We manufacture wire harnesses according to customer wiring diagrams, connector interfaces, wire specifications and installation layouts. From wire cutting and terminal crimping to connector assembly, protective sleeving, shielding, overmolding and electrical testing, each harness can be configured around the requirements of the finished equipment.
With 56 automated wire harness production lines and integrated capabilities in connectors, precision metal components, injection molding and finished assembly, Onlink supports both customized harness development and repeat OEM production.
Wire, Terminal and Connector Integration
The reliability of a wiring harness depends on how well the wire, terminal and connector work together.
Onlink's integrated manufacturing capabilities allow these components to be considered as one electrical assembly.
Wire Selection
Wire gauge, conductor structure and insulation should match the current load, voltage, operating temperature and installation environment.
Custom assemblies can use multi-specification copper conductors with insulation selected according to the project requirement.
Terminal Crimping
Terminals must match both the conductor size and connector interface.
Wire stripping and terminal crimping are controlled according to the approved harness specification to maintain consistent electrical contact throughout repeat production.
Connector Integration
Custom harnesses can incorporate specified automotive or industrial connectors according to the required pin assignment and mating interface.
Where a project also requires customized connector components, Onlink's Industrial & EV Connectors capability can be integrated with the wiring harness project.
Automotive Wiring Harness Applications
Custom automotive wiring harnesses can be developed for electrical connections throughout a vehicle platform.
Typical applications include:
Vehicle Control Systems
Harness assemblies connecting controllers, sensors, switches and actuators.
Motors and Auxiliary Equipment
Wiring for pumps, fans, small motors, electric actuators and other auxiliary electrical components.
Lighting and Accessory Circuits
Custom harnesses for lighting, switches and additional vehicle electrical equipment.
Thermal Management Systems
Electrical connections for cooling fans, pumps and other thermal-management components.
EV Auxiliary Electrical Systems
Custom harnesses for low-voltage control, sensors and auxiliary electrical equipment within electric vehicle platforms.
Equipment and Module Interconnections
Harness assemblies connecting multiple electrical modules inside vehicle subassemblies.
Each project can be developed around the actual connector interfaces, branch locations and installation space of the vehicle.
Integrated Supply for Wiring, Connectors and Molded Components
