A: This model is a modular unit that includes the housing and terminals. This allows for total customization, letting you choose the exact wire length and gauge (12-14AWG recommended) for your specific build, preventing the messy excess wiring found in pre-made kits.Q: How does the black housing help with maintenance? A: The black finish resists staining from engine oil and grease, ensuring that terminal markings remain legible and the unit continues to look like an original factory component even after years of use.Q: Can I use this for my boat? A: Yes! The WG33A is highly effective in marine consoles for managing accessory power. While the cover shields from splash and salt spray, we always recommend mounting it in a location not prone to full submersion for maximum longevity.

• Centralized 3-Way Power Distribution: The WG33A features a specialized 3-slot relay output architecture, allowing you to consolidate three independent electrical circuits into one secure hub. Each slot supports a heavy-duty 40A 4-pin relay paired with an ATC/ATO fuse holder, providing a streamlined control solution for high-wattage equipment like auxiliary lights, electric fans, and fuel pumps.
• Engineered For Under-Hood Integrity: Constructed from high-impact, flame-retardant materials (UL94-V0 rated), this relay box is built to withstand the extreme thermal fluctuations of an active engine bay. The rugged black housing resists oil staining and physical wear, ensuring that your customized power distribution center maintains its structural integrity during demanding off-road or long-haul trips.
• Clean Stealth Wiring Solution: Say goodbye to the cluttered "rat's nest" of wires around your battery terminals. This black modular box allows for a discrete, professional-grade installation that blends seamlessly with your vehicle’s factory plastics. It simplifies the wiring process, making it significantly easier to trace lines and perform routine maintenance on your auxiliary system.
• Weather-Shielded Protective Housing: Designed for the rigors of marine and off-road environments, the WG33A includes secure-fit top and bottom covers. This protective barrier provides physical shielding against dust, road spray, and moisture. By keeping terminals dry and clean, it prevents terminal oxidation and intermittent connectivity issues without the use of chemical additives.
• Universal Compatibility And DIY Ease: Compatible with all 12V DC systems, this universal relay block is an essential upgrade for any customized electrical project. It features integrated mounting ears for stable securing on any flat surface. Note: To ensure peak performance, we recommend using appropriate wire gauges (12-14AWG) and ensuring all pigtails are securely crimped during installation.
