i need some help

I heard about a lot of people having a GSR dash board in a EG hatchback...I was wondering is it a good or bad fit? I was also wondering what is needed to be done ( every little thing) to fit the GSR dash into the EG hatch...If anyone has a step by step picture instructions or a wiring diagram for the EG fuse box and the GSR dash wires please let me know...Thank you
