Overhead console temp/compass upgrade

[truckin 79]

Has anyone done this with a s-10 blazer overhead console that has temperature and compass? I bought one from the junkyard for 12, it is one of the short ones. I know there is a sensor probe somewhere in grill that I forgot to get. Does compass need any special wires or sensors I need to get? I like the over head lights,compass and temperature features. I looked in past posts but did not really see any explanation of wiring hook up. This is the type I bought do not have it hooked up yet.
