ej1allday

okay, so to start out my throw out bearing went bad so i replaced it while my car was running fine, then put it all back together and then drove down the road not but two blocks hit about 4 grand and it died, tryed cranking over but would budge, looked at it and the ecu fuse was blown, put a new one it and turned the car to the start position (didnt try starting it) and it blows the ecu fuse, ive been threw around 30 fuses trying to pinpoint whats making it blow we undid the whole engine harness and it dont blow, so its nothing in the interier then we plug in the engine harness and and disconnect everthing except the thermostat ground and it blows it. ive already tryed using a different motor harness and it still blows. please help asap thanks
