Replacing door lock and window switch???

[crawdad]

Hey guys. I've got to replace the window switch and the door lock switch on the driver side of my truck. The thing is, I can't figure out how to remove the wires from the old switch. I don't see anything to unscrew or anything like that that would allow me to unhook the wires. Looks like the only way to get them out is to just yank them out and I suspect that ain't right. I need an expert here to help me out please. Thanks.
