Wire
Upfitter Primary Wire
Ensure the absolute reliability of your fleet's warning systems with Professional-Grade Automotive Primary Wire. A $2,000 lightbar is utterly useless if the wiring harness supplying its power fails. In the severe environment of an emergency vehicle chassis—subjected to extreme engine heat, winter road salt, diesel fluids, and constant vibration—standard cheap hardware-store wire will quickly become brittle, crack, and short out. Our upfitter-grade primary wire is engineered specifically to survive these conditions. Featuring highly conductive stranded copper cores and thick, chemical-resistant insulation, it guarantees uninterrupted power delivery to critical sirens, radios, and emergency lighting systems during the most demanding pursuits.
Key Features & Upfitter Specs
- Stranded Copper Core: Constructed with highly flexible stranded copper, preventing the metal fatigue and breakage common in solid-core wires when subjected to severe vehicle vibration.
- Severe-Duty Insulation: Encased in a thick, abrasion-resistant polymer jacket (typically TXL or GXL spec) that heavily resists melting from engine heat and degradation from automotive fluids.
- High Current Capacity: Designed to safely handle the heavy amp draws required by massive 200-watt siren amplifiers, motorized lightbars, and high-output scene lighting arrays.
- Color-Coded Routing: Available in a wide variety of standard automotive colors, allowing fleet mechanics to easily trace complex wiring harnesses and adhere to standardized upfitting diagrams.
- Universal Application: The absolute foundation of any professional 12VDC installation, perfect for extending lighthead pigtails, wiring relay blocks, and fabricating custom power distribution harnesses.
