DaierTek 8 Pack 12V Relay with Built-in Diode & 12 AWG Harness Socket 30A/40A Heavy Duty SPDT 5 Pin Relay Switch Waterproof for Automotive Car Marine Boat

I bought these to rewire some of the stock relays in my vehicle while the wires on the pigtails were a little shorter than I had hoped they worked pretty good. Super easy to pull out the 5th pin for those who only need a 4 pin. They are a little hard to install the relay onto the pigtail but I think that's because of them being water proof and the rubber boot gives some resistance.

Good

These are NOT chintzy relays. They're the real deal. I've been using them a couple of years and they work like a charm.

A good general purpose relay. This one has the diode, if you don't need the diode it doesn't come into play.

Stout heavy duty relay, heavy gauge wire, weather proof seals, tight fitting connections. I've used them In the past with great success however this order is missing the mounting tabs.

Did not come with the mounting brackets shown in the picture.

Had to redo the relay setup for my plow lights and the chief issue was corrosion from salt and batteries i believe. These sealed u it's have so far kept the contacts nice and clean and the housing will accept other relays if need be.

Water proof and diode a great plus
