I have an 03 super duty 4x4 and was going to look into this swap. I can fab but not much experience with wiring. I noticed you have a custom sheet metal intake, used the 4.6 sensors with new harness, and reprogrammed the PCM for the increased engine size. Does this mean you just plugged up your old sensors and were ready to run with new programming or was there still a good bit of rewiring to do?
im American steel's friend and apprentice,
the stock ECU plugged into the factory crown vic's harness and the water temp sensor was left un used because the 6.2l does not use ECT. the ECU was tuned for the displacement and fuel trimming the motor required its not a hard swap especially in a truck with so much room lay the factory harness on top of the engine you can use every thing. no need to re wire anything.
