1999 ? jxi?convertible coolant sensor-no working fan.now worse!

I overheated yesterday and found the fan wouldn't run. I got home only to jump the fen at the fan- IT WORKED. Problem is I didn't disconnect the speakerwire from the power and twist it together to test the fan from the engines coolant sensors receptacle. Hence, I have power but in the car were it says door,ect. , it said NO BUS and the car doesn't even turn over. What do you think I did and what can I do!
I checked all the fuses.they are good... I here relays clicking but car wont turn over. 12 volts up the coolant sensor line. Where does it go wrong.
