When you’re tracing a dead light or adding accessories to your tractor, having the right wire on hand makes all the difference.

The bright blue color makes it easy to identify your circuits and follow wiring diagrams that call for specific colors.

What You’re Getting

  • 45 feet of professional-grade 18-gauge primary wire in bright blue
  • Flexible stranded copper conductors that resist corrosion and metal fatigue
  • Durable vinyl insulation that stands up to engine heat, cold, and moisture
  • Perfect gauge for low-amp circuits like lights, gauges, and control switches
  • Easy-to-spot blue color for following wiring diagrams and identifying circuits

Built for Real Farm Work

This wire handles the electrical loads you’ll find on tractors, combines, balers, and other farm equipment. This 18-gauge wire handles the lower-amp circuits you’ll find powering dashboard lights, work lamps, turn signals, and other electrical accessories on just about any piece of farm equipment. Whether you’re wiring LED work lights, connecting cab switches, or repairing damaged harnesses, this wire keeps your 12-volt systems running reliably.

Made to Last

Farm wiring takes a beating from heat, cold, moisture, and constant vibration. This primary wire uses quality copper conductors and durable insulation that stands up to the harsh conditions under the hood and around the farm. The multi-strand design stays flexible even after years of use, so connections don’t fail from metal fatigue.

Installation Notes

Always match wire gauge when splicing into existing circuits—mixing gauges can cause voltage drops and overheating. A good crimp tool and heat-shrink connectors make professional repairs that’ll last. Don’t forget to disconnect the battery before working on any electrical circuits, and keep some electrical tape handy for finishing touches.
