The N55 435i Install is pretty straight forward. I agree on the video though, they really need to do one start to finish with the new N55s. Too bad BMW didn't use traditional ECU wiring so we can make undetectable clips for the ECU. I'm still looking for the best way to T into the ECU so I can take it in for maintenance with a 15 min uninstall and not worry about them finding it, then again I doubt the guys at the dealership would pull the ECU out with OBD port diags.
