Frequently Asked Questions
OEM wiring harnesses are the ideal solution for rewiring your equipment, machinery, or vehicle using original factory specifications. These harnesses integrate perfectly into your product. You can incorporate supplementary harnesses for factory-fitted options, which connect seamlessly with the main harness. With OEM harnesses, you can order individual harnesses as needed, rewire specific sections, or perform a complete rewiring of your equipment.
Our harnesses are completely assembled and produced according to the original specifications. You can proceed directly with installation, connecting each harness to others to finalize the wiring systems of your equipment or machine.
We advise installing a new harness while removing the old one to ensure accurate routing and connections. If the original harness is unavailable, obtain an assembly manual as a reference to recreate the factory wiring layout.
A donor harness consists of either the original wiring harness or its specific authentic components, which OEM manufacturers may require during the production of a new unit. Should certain components be unavailable or need to be recreated, manufacturers might utilize these parts from the existing harness. Except for one or two serviceable components from the donor harness, all other elements—including connectors, clips, wires, cables, terminals, etc.—are entirely new in the newly engineered harness.
