I had Brian at AHH to earth out the door jam 3 min feature single wire...this appears to be linked into the harness he made for me. My personal opinion? what a PITA feature to even have, mine turns off with the ignition when I park and lock up etc. My Harness was about 1.2 meters in length to cover distance to the amp under my drivers seat. I did snake the wire from that single Connector though as I was thinking JUST IN CASE but its a mute point for my Harness set up. Mine was quite complicated adding a FV camera junction box into the mix and works very well in unison with the MY19 HU large display via a 3 position switch. I intend to be remod to the Enter/View button as a further custom hack for a factory feel using a 10 second relay in line. Why do I do this to myself?
