Overview

12V Waterproof Relays 40A 4-Pack 5-Pin with Wiring Harness and Metal Mounting Bracket

1. All-in-One Kit

This kit streamlines installations by bundling four relays with matching wire harnesses, saving you the hassle of shopping for components separately. Whether you're wiring multiple accessories or building a complex control setup, everything you need is right in the box. This cohesive package guarantees consistency and compatibility across all four relay assemblies, simplifying both installation and maintenance.

2. Reliable SPDT Switching

Each relay in the kit is a standard 5-pin, single-pole double-throw (SPDT) Bosch-style design, capable of handling high currents—40 A. This makes it versatile enough for a wide range of applications, from powering lighting to controlling high-demand accessories. The SPDT configuration gives you both normally open and normally closed options, offering flexibility in circuit design.

3. Durable Construction

Built to withstand tough environments, each relay’s sealed plastic housing provides excellent protection from moisture, dust, and road debris. The included metal mounting tab allows quick and secure fastening under the hood, behind dash panels, or in marine compartments. This rugged construction ensures long-lasting performance even in extreme conditions.

4. Plug-and-Play Harnesses

The included wire harnesses come pre-assembled with standard automotive connectors that match the relay pins precisely, making installation as simple as plugging in. This plug-and-play design reduces installation time and errors, making it ideal for both professionals and hobbyists. Color-coded wires and clear labeling further enhance the user experience, ensuring quick and correct connections.

5. Ideal for Harsh Environments

Thanks to the waterproof sealed housing and sturdy metal brackets, these relay kits are tailor-made for environments exposed to water, oil, vibration, or extreme temperatures. Whether you're wiring winches on your off-road rig, pumps on your boat, or lighting on a commercial vehicle, this kit can handle the elements. Its reliable construction offers peace of mind in applications where durability and performance are critical.
