installing boost guage

ok, i was wondering if any1 knows how to install a digital boost guage because the boost guage on the GTP's is just stupid ( it looks cool but its stupid) so it would be great if there was a website with directions to all the vacuum linesi need and stuff, or just tell me how to do it. By the way the car is a 2000 grand prix GTP
thank you, Chris
