Pre-Wired & Color-Coded for Instant Installation Skip the tedious wiring work! Every Sulaims relay box comes factory pre-wired with 12 AWG heavy-duty wires—built to handle up to 20A continuous current without overheating. The wires are clearly color-coded (red for power, black for ground, blue for signal) for intuitive connections, so even beginners can finish installation in minutes. Plus, we include 9 assorted fuses, a relay puller, and 5 cable ties in the package—everything you need to get started right out of the box. 3. Splash & Dust Resistant for Harsh Environments Sealed with a durable snap-on cover and a tight rubber gasket, our relay box delivers reliable splash and dust resistance (ideal for engine bays, marine setups, or outdoor applications). It shields your electrical components from rain, dirt, and corrosion, preventing short circuits and extending the lifespan of your accessories. Note: Not fully submersible—perfect for above-water installations like UTVs, boats, and RVs. 4. Dual Protection for Maximum Electrical Safety Safety is our top priority. Each circuit is protected by a dedicated fuse that blows first to guard against overcurrent, preventing damage to your valuable devices (e.g., LED light bars, winches, water pumps). The 12 AWG thick wires minimize voltage drop and heat buildup, ensuring stable power delivery even under heavy load. Rest easy knowing your vehicle’s electrical system is in safe hands. 5.
