that B pillar got small sharp metal piece.. almost poke my fingers..
power cable on A pillar driver side. power tap using micro fuse tap on fuse box.
Power +ve constant tap at Horn fuse.
Acc +ve tap at ACC power plug fuse.
-ve attach to ground bolt.

Z40 comes with electrostatic sticker, which is good, wont damaged tint if needed to repsition/remove.
rear camera cable is plenty length, need bundle up and tie somewhere.
hardwire cable also plenty length. bundle up and tie inside dashboard.
even the included usb-c cable is plenty length.
all working fine, except need to monitor car KEY-FOB sensing.. as after install, sometimes 'no-key' appeared on cluster.
maybe cable routing interfered with key-fob sensor..
