Creating wire object

Question

I have to create a simple Circuit simulator. I have figured out how to create almost all objects (like power sources and etc. ), but I can't figure out how to create wire object. 
Wire functionality:  

• connect two objects
• Select wire and manipulate it or delete it

Problem is, that i can't find a way how to draw the wire. DrawLine function would not work for me, because after drawing the line I simply can't manipulate it. So at this point I'm open for suggestions. 

(If there are some mistakes, sorry, I'm not native English speaker)
