I mounted mine...
I mounted my TST box w/ cable ties just below the hood release. I pulled the lower dash pan out at top and routed remote cable behind it. My remote is sits on the guage cluster clear plastic on the far right. I did not attach the remote to the clear plastic; it just sits there. Visible, easy to adjust and reach.
FYI: using the adhesive backing will not stay attached in heat (experience).
