Hello Shew, I purchased mine directly from logolite. I mounted mine directly to my steering column on the very bottom, easy to reach and kinda out of sight. I secured it with 2 or 3 zip ties with a rubber pad to hold it in place, there is also a strong magnet on the unit to hold it in place. As for power connection I went right off my junction box on the firewall, was an easy setup. The unit has been on for a few years and Ive had no issues at all. Good luck with yours and Happy Motoring,
Dutie
