irhapsody 4-pin 40/30AMP 12V Relay Kit, Spst 12-Volt 12-Pack Automotive Relay, with Interlocking Harness Socket Holder and Heavy-Duty Pigtail

I have 2 of these on my truck powering and controlling some aftermarket accessories and they do a great job! Easy to work with and understand with some entry-level electrical knowledge. The wire gauge is accurate and makes for an easy connection no matter how you decide to connect it. Haven't had an issue with water damage or corrosion so it's safe to say the seals are good! Gonna use these for any future projects I have that require this type of relay.

Does what it does

I'm using this to run a Viair compressor on my truck via a Rough Country air bag controller. It turns the compressor on and off when the controller tells it to. Does a great job. I like the high gauge wire as it allows me to run the compressor, which can go up to 20 amps. Wiring is easy and straight forward. It just works.

We originally bought these to bypass a burnt terminal that was causing a fan issue in our Mustang. We found another issue and didn't use them for that but they are well made. We did use one to fix a trim relay on one of our boats. Worked well for the tabs.

Works great, using these for adding lights on sxs.

Bought these for some electrical mods ended up using it to replace current relays. honestly they work phenomenally

desde que los uso, mi carro dejó de tener fallos

Being a mechanic I am always needing relays for added fans, lights, horns, whatever. A 6 pack with pigtails and mounting lugs just makes it so much easier than sourcing them from the parts store when needed! Great simple SPST relay for putting power or ground to whatever you need with a low voltage signal from a switch inside the vehicle or tapping into a signal under the hood without overloading the source circuit. Just remember to add a fuse!

Just like described, comes with nice detailed instructions on 4 different ways to wire them, also came earlier than they had said which was nice
