They certainly have what they look like and a great seal around them. Keep in mind that I would put them together before installing. Because once the two parts are put together, they don't want to fall apart. (There is a relay part and a wire harness part) Even with silicone gel they didn't separate at all. I suspect the design is such that if one relay fails you can connect another without having to redo all the wiring. With this in mind, I received 5 packs, although I will only use two or three.
