Gebildet 2pcs 40/30 Amp Waterproof Relay Switch 12AWG Harness Set with Built-in Diode- 12V DC 4-Pin SPST Automotive Relays Hot Wires

Good quality with well crimped connections. Tested and wor absolutely perfectly. recommended. Very easy to install to 12 volt vehicle, no idea about other voltages! Works exactly as they should.

Good quality fast delivery

Would have given it 5 starts but on the ones I recieved two of the coloured wires did not match up with the diagram. Red connected to 87 not 30 and Blue connected to 30 not 87. Apart from that it works great and easy to set up.

Super easy to fit and job completed in no time working perfectly 👍

These relays are better than I imagined they would be, they come with the holder/socket and metal mount that is not fitted (in case you would prefer to panel mount). The socket has a good length of decent gauge colour coded wiring and it is weather sealed between the socket and the relay. The relay assembly is slightly larger than you'd probably expect but these are 30/40 amp rated - all in all they seem great quality. I bought a load of these for a project and every one worked perfectly, totally happy with these and will definitely purchase more when required.

Worked perfectly to use in conjunction with magnetic lock on drive electric gates.

Good quality with all needed fittings and relay body clearly labelled.

The relays work well and the wiring harnesses are fine. However, you are forced to test them before use because there are no wiring diagrams provided, no markings on either the socket or the relay to indicate which pair are the coil wires and which pair is switched.
