<VV> Corsa dash Install help

[rich dixon]

Hi: Does anyone know of or have  detailed step-by-step instructions on how to install a Corsa dash in a Monza.  I am looking for details as how do you modify the dash wiring harness for the tach and clock. Where do you connect the vacuum line on the engine for this gage? The head temp gage, what required to make this operational on a Monza. Does anyone offer a install kit for doing this?
 
I know what's needed, just looking for the details as to how to do it. 
 
Thanks
