MODEL 6858: 10-GAUGE EXTENDED LENGTH AIR COMPRESSOR WIRING KIT

HEAVY-DUTY AMPERAGE ELECTRICAL ARCHITECTURE FOR LONG-WHEELBASE RUNS

Establish a rock-solid, high-current power path across long-wheelbase vehicle setups with the premium Kleinn Model 6858 Extended Air Compressor Wiring Kit. Explicitly engineered to safely deliver clean power to heavy-draw automotive air systems over longer distances, this master electrical installation package features a massive length of premium 10-gauge structural copper infrastructure wiring. By minimizing voltage drops and eliminating electrical bottlenecks on long wire runs, this kit ensures your heavy-duty compressors start up immediately and run at peak performance without overheating your vehicle's factory electrical layers.

UNIVERSAL LONG-REACH HIGH-AMPERAGE POWER HARNESS

The Model 6858 is heavily curated with essential electrical baseline components to simplify your plumbing from bumper to bumper. Featuring a specialized 12V 30/40 amp 5-pin SPDT automotive relay and a dedicated pre-wired socket harness, this network safely separates your cabin controls from high-amperage current spikes under the hood. While optimally optimized as the official companion wiring array for Kleinn train horn systems, this versatile master installation kit can also be deployed in any custom 12V application where switching high-amperage auxiliary devices is required across extended frame rails.

Why Choose the 6858 Extended Wiring Kit?

  • 26-Foot Extended 10 AWG Line: Packs a massive 26 feet of premium 10-gauge power wire, supplying the long, thick cross-sectional current path needed for full-size crew cabs, long-bed trucks, and SUVs.
  • Inline Safety Protection: Equipped with an integrated heavy-duty ATC fuseholder and a matching 30-amp ATC blade fuse to defend against sudden short circuits over long wire lengths.
  • Isolated Relay Infrastructure: Packs a commercial-grade 30/40 amp 5-pin SPDT relay with a dedicated socket, shielding cockpit controls from high current loads.
  • The Terminator™ Switch Included: Bonus inclusion of the legendary Model 320 all-metal brushed nickel flush-mount horn activation push button for clean dash styling.

THE VERDICT: The definitive long-reach electrical foundation for any high-output air network. The Model 6858 marries extended heavy-gauge current capabilities with a vital safety fuse and control relay, ensuring your onboard air installation remains secure, efficient, and completely fire-safe across large vehicles.

What's Included in the Box

  • Main Power Wire: 26 Feet of premium heavy-duty 10-gauge structural power wire (Extended length).
  • Circuit Protection: Integrated inline ATC fuseholder equipped with one (1) 30-amp ATC blade fuse.
  • Control Module: One (1) premium 12-Volt 30/40 Amp 5-pin SPDT relay and matching socket harness.
  • Signal Wire: 5 Spools of high-utility 18-gauge relay, pressure switch,  and horn activation wiring.
  • Cockpit Trigger: One (1) Model 320 "The Terminator" brushed nickel flush-mount momentary horn switch.

🔴 PRO TIP: Tailor your wire routing seamlessly to your chassis length. This extended 26-foot wiring bundle is custom-tailored to handle complex routes along frame rails. If your vehicle layout is more compact and does not require an extended long-reach line run, you can utilize our standard 14.75-foot power line setup by choosing Kleinn Part #6852 Wiring Kit.
