I read through again and see where there's still some question as to if it's the same wire as the amp in the trunk given people report the amp wire stays on.Red wire in right VC switches off when weight is removed from driver's seat and car is locked. Sentry mode does not affect the power status. Its off when the car is "unoccupied", on when it is.
Lets say the small wire in the lower passeneger side bundle is on/off with driver side seat occupancy / initial brake use since there's multiple reports of that being the behavior, but not call it vc right or amp wire since it's not fully clear if it's either/that those are the same wires.
Also, annoying I can't go back to edit.
