got a 97 gmc with an overhead console, noticed that infront of the 2 round lights mounted in the console, there is a slot that has nothing in it. i was looking on here and noticed someone hade a factory gm digital display mounted up there, like one off a jimmy or envoy, that tells you temperature, mpg, and compass. I was wondering if anyone hade done this before? how do you hook up the mpg gauge?
