I've just acquired my newest project its a manual 99 gt with the 4.6 I want to know if I can just get the engine and trans from a 2011 to 2014 gt and use it if not what transmission should I go with and what kind of wiring harness do i need to get. This is my first engine swap and first mustang I've worked on cars for awhile now so I'm not going in completely blind so any tips on what will make this easier and what I can expect to run into if you've done this swap to would be greatly appreciated
