We got tired of cheap-looking wiring kits that use undersized wiring and crappy relays, so we just put our own setup together! Everything you’ll need and nothing you don’t, at a great price. 20 feet of 4 gauge copper welding wire, pre-terminated with copper lugs and heavy duty shrink tubing. 100A marine-grade circuit breaker. 25 feet of 18 gauge ignition signal wire with fuse taps and connectors. 10 feet of 18 gauge ground wire with connectors. This wiring kit is designed for Viair dual compressor packs, Air Zenith dual compressor systems, or any other power supply needs up to 80 amps. We’ve included only the highest-quality components to ensure safe and trouble-free operation at the lowest cost possible.
