1.How to choose a good relay

its quality mainly depends on the material and technology, choose a silver contact point makes the working life much longer, and machine core use pure copper wire, 30 and 87 pins use copper material too, then the relay can be used for 5-8 years. If add one more braided wire ,the power will be larger, so as the working life . If need matching with the OEMs , you can choose a larger particles of silver contact , using longer, but the price will be higher too .
