Ps2 mouse revival

Last night my dog started chewing on my Logitech PS2 mouse plug and now it’s not working any more (the mouse, not the dog). Since this is the best mouse I ever had and I paid 50 $ for it, I would really like to have it fixed. So, right now I have 4 wires (white, blue, orange and yellow) coming out of my mouse and I would like someone to tell me how to connect these to a standard PS2 plug (something like red-1, blue-3 etc.)
