Review for: 5 Pack 5-PIN 40/30 AMP 12V DC Automotive Relay Kit Harness Socket - Heavy Duty 12 AWG SPDT Waterproof Relay Kit Tinned Copper Wires, Automotive Relays for Boats Auto Fan CarsBrand: DAYMAKERAppears to be working just fine. I am using these relays in home made low temperature controls for charging LiFePO4 batteries. Current draw for the coil was measured to be about 140 milliamps at 12 volts, a bit higher than I would like for my application, but should be fine for most automotive use. I am only running 5-10 amps though the contacts so can not say if the relay will hold up to full power rating.The socket appears to be waterproof, the fit is very tight. Wires are a bit short, as seems to be normal with pre-wired devices like this. I would rather simply have screw terminals than need to use crimp connectors, but they are functional and have heavy wire for the load leads. Overall, this relay will do what I need.I will update this review if I find issues with the relays.

So far these relays are doing a great job for a lighting project. I wanted something waterproof for under my hood, and the seals seem very nice. The wires are thick, and the diagram that came with was easy to follow. So far these are working perfect for my needs, and the mounting tab made it easy to secure it against the firewall.
