Review: Good wiring relay - ​I recently used these relays for a complex 12V project involving high-draw accessories, and they have performed flawlessly. The build quality is impressive for the price point, and they feel much more substantial than the standard non-waterproof versions. ​What Stands Out: ​True Weatherproofing: The rubber seals on the sockets fit tightly around the relay base. This is a game-changer for any wiring located in an engine bay or exposed chassis area where moisture and road grime are inevitable. ​Heavy-Duty Pigtails: The wiring leads are high-quality and pre-stripped, which saved me a significant amount of prep time. The gauge is appropriate for the 40/30 AMP rating, handling the load without any noticeable heat buildup. ​Secure Mounting: The integrated metal mounting tabs are sturdy and don't flex easily, allowing for a very clean and secure installation on a firewall or inner fender. ​Clear Wiring Logic: The standard 5-pin SPDT (Single Pole Double Throw) configuration makes them incredibly versatile for both normally open and normally closed applications. ​Final Verdict: ​Whether you are setting up auxiliary lighting, fuel pumps, or custom cooling fans, this 5-pack offers incredible value. They provide peace of mind knowing the connections are protected from the elements. I’ll definitely be keeping a few of these as spares for future projects.

### ⭐⭐⭐⭐⭐ Good looking relay units for the price.
*by D***E on September 8, 2025*

I haven't had a chance to use them yet, however I examined one last night. They appear to be a very high quality unit. The pigtails on the plugs are 16 ga wire and they are sealed into the plug base. There's a nice silicon gasket that seals the plug into the relay bottom. It is also numbered as to what the terminals do. The wires are color coded, red for the power in, black for ground etc. I think they are yellow, blue, red, black and white. The relay itself has and sturdy mounting lug on the top of it as well. I think they are rated for 30 amps? The set comes with a schematic showing four different ways to wire them up. These are a five pin relay. The instructions say to leave the center terminal 87a disconnected. I've never used that one so I don't know what it does. You get five of these relays in a box and for the money I think it's a good buy. If the relay part of them stands up I'd recommend them.
