The video below shows you where to run any cables you are looking to get through the firewall on a MK7 model. This was shown on a GTI but would likely also apply to Golf and Golf R models. Most commonly you would need this info if you were running a line for a boost gauge or if you are trying to get an amp power cable to the battery for a stereo system.
We also posted pictures below this video in case you would like to share them with anyone who might find them useful.
