OK I have a 2001 GP GT and it has a DIC in it but it's just the picture of the car for the door lights etc.. I want to change it to the DIC with the MPG, oil life all that good stuff do I need to splice any wiring for this or is it just a swap? I did read the first few pages but I just want to make sure before I spend cash on it if it's not going to work! And my father had a 2003 GTP and I didn't find the HUD to be worth the money or time to drop it in a GT it's actually kind of annoying IMO. Thanks
