thank you.

 

Not an installer, but these cables work great with the powered mirror on the GTR:

Easy switchable power (goes off when car does) for the V1, which then you can mount as usual or use one of these mounts that attaches to the mirror

Ditto that recommendation. Easy, clean, DIY install.
