Is the 12 volts on the ECU case 'real' or just measured with a meter? Connect a small 12 volt bulb between the case and a good earth, or lightly brush an earthed wire against it and look for sparks to check.
Short answer is that the problem is whatever you wired wrong, which may or may not have caused further damage.
Are the two cables to the battery connected correctly. Red to battery + and brown or brown/orange to battery - ?
