I just got B1W.
Looking to get the hard wire kit. Not sure whether to get the 2-wire or 3-wire kit. As I know the ACC wire is not used. So 2-wire kit should be sufficient, right? However some says the ACC wire might be used in the future.
FYI, the 3wire kit is double the price of 2 wire kit. I just don't want to waste money if the wire is not needed.
Is this 3-wire kit good enough?
