You would either have to cut the dash to fit the HUD cover, or you would just need to buy a dash out of a parted out GTP.

I am not sure if all harness' are the same with all the connectors.... it is possible you have the connectors for it in the dash already..... but if not I would pick up a dash harness out of a GTP as well.

then this should just be plug and play.....

hope that helps.......
