6) Does it spark? If so, something is drawing power. If not, there could still be a tiny bit of draw.

You’re all good until step 5. If you really want to know if you have a draw and what that voltage draw is you should use the two test leads of a multi meter set on DC volts. Connect one to the battery and one to the disconnected cable. Any voltage above ten volts is a draw that will draw down the battery over a short time. If you have a 10-12V draw start removing the fuses in the fuse box one by one until the draw drops or goes away. That will steer you in the right direction.
