Do we need to do reprogram anything and disconnect main battery?

Hi, everything i did, is covered in the video. i didn't disconnect the main battery but if you wish to be extra cautious the you can. I didnt need to do any programing, I did mention at the end of the video that you may need to delete fault codes with an obd2 computer.
