Take your terrarium to a local glass shop. They can drill (or cut) a small
opening in the side of your terrarium so you can run the power cord through
(you may have to clip off the plug and then splice it back on when you feed
it through the hole).
Do NOT drill through the bottom of the tank (especially important if your
terrarium is a fish tank convert) as most fish tanks have tempered glass
bottoms. Touch this stuff with a drill or heat and it will definitely
shatter.
Good luck!

Used a grinder, ground a notch out of each top...works great.
