Any guides to do this?
Link here to JA's mod. He's pretty much an electrical guru on the 4th gen. He has lots of other electrical mods on his website.
This is interesting, thanks. I guess the only problem will be that I do have a USB hub and Hard drive that are wired to the cig lighter outlet in the front. I would have to split it because I dont want hard drives spinning and hub on when key is not in.
