So just bought n new 2017 AT and want to add some power ports. after reading this thread I'm a little confused about how to go about it. The OEM has a Y that I assume is for a second port? I will want to use to charge my phone and possibly a GPS at a later date. Should I go ahead and order the OEM unit or hard wire to battery and leave live?
Not an electrician so I'm asking for advise.
