Removing the plastic trim was not trouble at all. Just open at the bottom side first in the middle by using a credit card or flat screw driver. Again slowly at the top middle above mirror holding pivot. They should come apart with little bit of wiggling.
Wire tap is done per the picture attached (4015 harness red wire to bottom mirror harness red wire at right end; black wire to brown wire on left hand side of mirror harness). It powers off with in 5 mins of locking the car, at the same time as the glass control knob lights off. Using the 2 zip ties provided, tied the harness way close in the beginning where they are inserted in so that hooked in wires won't come loose , another at the top trim end point, tied to 2 other harnesses so no one pull it out.
