Custom Wire Harnesses for Agricultural Equipment OEMs

Affiliated Products manufactures custom wire harnesses and cable assemblies for ag equipment OEMs across North America. From tractors and row crop planters to sprayers, combines, and grain carts, our assemblies are built to handle the long hours, vibration, UV exposure, and moisture that field equipment demands day in and day out. Whether you have a finalized spec or a rough concept that needs prototyping, we’re ready to build it.

Wire Harnesses Built for Agricultural Conditions

Farm equipment wiring lives in one of the harshest environments there is — baking in the sun, soaked by rain, shaken constantly by rough terrain, and exposed to chemicals, dust, and debris. Every agricultural wire harness we manufacture is built with those conditions in mind:

  • Abrasion-resistant and UV-rated cable jacketing
  • Sealed connectors rated for moisture and dust ingress (IP-rated interfaces available)
  • Vibration-resistant terminations using Deutsch, AMP, and Molex connector families
  • Wire gauges from 0.5 mm² to 16 mm² to support lighting, control, sensor, and power circuits
  • 100% continuity tested before shipment

Equipment We Support

Our agricultural wire harness assemblies connect the electrical systems in:

  • Tractors (cab, engine, lighting, and implement interfaces)
  • Row crop planters and seeders
  • Sprayers and chemical application equipment
  • Combines and harvesting machinery
  • Grain carts and auger systems
  • Irrigation controllers and pump systems
  • Precision agriculture sensor networks

If your equipment runs a wire, we can build the harness for it.

OEM Manufacturing from Prototype to Production

Affiliated Products works directly with ag equipment OEMs at every stage — from a first prototype run to full-scale production. We build to customer-supplied drawings, connection sheets, or samples, and our team will review your design for manufacturability before we begin. Our manufacturing process is certified to IPC/WHMA-A-620 standards, so your harnesses meet the quality benchmarks your procurement team requires.

Located in Mayville, Wisconsin, we’re centrally positioned to serve OEM manufacturers throughout the Midwest and beyond.
