Help please to edit a component in inkscape and then use it

Even though you didn't ask : connect wires to the relay. As you see the result isn't exactly intuitive for the newby. I'm of the thought that having the breadboard wires connect to the silkscreen connection circles on the part would be a lot better than to the real physical terminals as at present. Coming at this cold (without having drawn it ) I'd have a hard time figuring out what the connections actually do.
