My sollenid went bad on my Murray mower. My model number is 325007x92. Where am I supposed to hook my wires to? Where does the black wire (ground?* go, where does the starter wire (big red) go, where does the orange wire go (I believe this is from the switch), and where does the small red wire go (for blade?)? Also could someone tell me in what order do they need to be put on and does each one need to have a nut between them when they are hooked up.

Look on your starter and see what color you have coming from the post on the side of it.
