You need to slow down because your all over the place with this problem and your skipping important steps. You never answered the question from entry point #10 about the turn signal converter. You needed to leave the TSM unplugged after you found that the fuse still blows and take the next logical step. I can't demand you troubleshoot the problem the way I would do it because it's your bike.
If you have a better plan, then go for it.
The U1064 is irrelevant at this point and means nothing because you booted the ECM with the TSM disconnected. If you want to clear the code just follow these instructions, but with the fuse still blowing it may not.
