Stiletto

So I'm wiring up a switch that I'm going to put into my center console to turn on/off my stereo amplifiers. I want to make it look stock, so I found a blank console switch with wiring, and I bought a new socket to plug the wiring into:



Unfortunately, the socket is only the plastic piece, and does not come with the metal contacts that the switch plugs into (which are then soldered to my amplifier wiring). Looking online, I've got three possible part numbers for these little metal contacts:



But I'm not sure which one to order. Anyone have an idea which of these is the right piece?
