And if you want to be cheap and lazy . . .
Ok, ok, it is me who tends to cheap and lazy . . . .
You can usually put crimp-on ends -- female spade terminals in this case -- on the wire ends and just put them straight onto the male spade type terminals coming from the relay.
No socket needed.
They can carry the current if the wire can -- typically #10 AWG for 30 amps -- I think the insulated female crimp-ons will be yellow for #10 wire. Stranded (as opposed to solid) tends to work best.
