Fenix Manufacturing Solutions builds custom wire harnesses and cable assemblies for U.S. OEMs from a free trade zone in San Pedro de Macorís, Dominican Republic. Cutting, stripping, crimping, ultrasonic welding and electrical test run under an ISO 9001:2015 quality system, and finished assemblies ship duty-free to the United States under DR-CAFTA.
You send the drawing, the wire list and the connector part numbers. We build the harness, test it and ship it. Fenix has assembled harnesses in the Dominican Republic since 1987, for customers that include ABB, Cummins, Kawasaki and Honda.
Harnesses leave our floor already integrated into the unit when the program calls for it, because electromechanical and box build assembly runs in the same plant.
Bundled wires, cables, connectors and terminals built to your drawing, with sleeving, grommets and strain relief where the application needs them.
Multi-conductor cables, shielded or insulated, for power delivery and data transmission.
Wire marking by number, letter or color code, plus printed tags, heat-shrink tubing and wrap-around labels for traceability and part identification.
Installation of the finished harness into the enclosure or subassembly, on the same floor, so the unit ships complete.
Every step is documented and repeatable. The verification column is what you ask any harness supplier for before you place an order.
| Step | What happens | How it is verified |
|---|---|---|
| Cutting | Wires and cables trimmed to the lengths on your drawing. | Length check against the wire list |
| Stripping | Insulation removed to expose the conductor for crimping or soldering. | Visual inspection for nicked strands |
| Crimping | Terminals and connectors attached by press to the stripped ends. | Crimp force monitoring on every cycle |
| Tinning | Solder applied to stripped ends to prevent oxidation before terminal application. | Visual inspection |
| Ultrasonic welding | Wire ends bonded without solder using high-frequency vibration. | Pull force testing |
| Final electrical test | Continuity and insulation checked on the finished assembly. | Hi-pot testing; TDR where signal integrity matters |
A harness revision is a drawing change, a new connector and a new crimp setup. In your time zone that is a morning. Eleven hours away it is a week.
Harnesses that meet the rules of origin enter the United States without tariffs under DR-CAFTA. We check the bill of materials against those rules while quoting.
Harnesses are bulky and light. Air freight from the Caribbean is a cost you can plan for; air freight from Asia is the cost that eats the saving.
A wire harness is a bundled arrangement of electrical wires, cables, connectors and protective components that transmits power and signals within a system. Bundling the conductors into one assembly improves organization and durability, and it turns a long wiring job on the production line into a single part that drops into place.
The harness drawing, the wire list with gauges and lengths, the connector and terminal part numbers, any test requirements, and your expected annual volume. If the design is still moving, send what you have. We come back with either a quote or the specific questions that are blocking one.
Crimp force monitoring measures the force applied on every press cycle and flags any crimp outside the window, so a bad connection is caught at the station rather than at final test. Pull force testing then verifies the mechanical strength of the completed termination against its tensile requirement.
Yes. Hi-pot testing applies high voltage to confirm insulation integrity and detect breakdowns across the assembly. Where signal integrity matters, time domain reflectometry locates breaks, shorts and impedance mismatches along the cable rather than just reporting a pass or fail.
They enter duty-free under DR-CAFTA when the finished assembly meets the agreement’s rules of origin. Manufacturing location alone does not qualify a product: it has to meet a tariff shift or regional value content rule, and the importer has to be able to document it. We review the bill of materials against those rules while quoting.
