Does anybody in the group have a digital OAT indicator?

We've just put a new single piece windshield in our plane and moved the
standard OAT gauge to the pilot's side window. Now we've decided to put all
new 1/4" side windows in and rather than drilling a hole through a brand new
window, I'd like to consider one of the digital OAT's such as Davtron or EI.
I'm wondering exactly how they are installed and where the temp probe is
located.

Thanks,
Jim
