OBS Jedi-Do Good
good work so far but yes you will have to run the new wire outside the taped bundle but should still be in the plastic conduit whenever possible. It would be okay two splice at the ends assuming the terminals weren't the problem but it sounds like you have a plan. If you had the battery disconnected that would have wiped your codes too. Go for a few test drives to besure your light stays off.
