For the most part it's personal choice and convience. If the existing wire is 12 or 14 gauge, you shoulldn't have any problem tapping into it, which is what I did. Also you should up the amperage for the fuse. The pusher fans don't do half the job a good puller will do, however, I do like the look of the pushers and have them installed on my car.
