Hi everyone. I have a few questions about my swap. I have a 2009 mustang gt that I recently destroyed the engine in, so I bought a complete gt500 engine. It came with the engine harness and thats it. I have done some research and understand that I need the smart junction box PCM and main body harness. My question is when I asked the dealer about the main harness they had no clue what I needed. He said that there is several harnesses that control the body. Do I need the dash harness? If so does the dash harness start at the PCM? Also does the gt500 use a different radiator than the standard gt?
