The NAC12N Grande Wire Harness is designed with performance-grade materials and smart engineering to bring out the full potential of your Nacho lighting system. Using TXL grade 12-gauge power wires and 18-gauge trigger wires, it ensures clean, efficient power delivery straight from your battery. The harness includes dual 40-amp automotive relays and a fuse block with a 40-amp fuse to protect your system from overload while maintaining consistent output. Every wire is wrapped in braided sheathing for maximum abrasion resistance and long-term durability in harsh environments. Two Carling switches, one 3-way and one 2-way, come preconfigured to control all three functions of your Grande lights, giving you full lighting flexibility right from the driver’s seat. A dedicated green wire also supports the Quatro’s running light function, making this harness compatible across multiple Nacho products.
