Where to get good Intercooler Temp Gauge or DIY?

[oazntoyo]

Well I want to setup an Intercooler Temp Gauge that shows a Digital LCD display of both in and out at the same time.

Similar to this: http://www.i-m-racing.com/noname26.html

Problem with that is it only shows one reading or the other or the differential. Not both.
I'm new to this community so I really don't know if anyone already makes one or has a write-up. Pretty much I'm looking for a clear digital lighted display similar to the product above if possible. Or just have digital displays hanging around without any alarm functions and what not.

thanks in advance
Mark

radio shack sells stuff like that. ( there suposed to be used for outside/inside temp but im sure it would work fine )
