I finally installed my trunk release 2 weekends ago. The install went flawless. I drilled a hole under the light switch and wipers switch on my 69 Dart for the button. Look fairly factory, in my opinion, and is a great addition to my car!
A decent button placement I've seen... The car had remote hood release under the dash so a small bracket was added onto the side it. Bezel appearance nearly the same as is in the glovebox wall. In the end I decided I'll cut mine into the top of left kick panel.
