Engine Swap/ECU question
I just recently purchased a 4.6L 3V engine, transmission and transfer case from a 2010 F150. I have a 2007 with a 2V 4.6 and a 2005 with the 5.4 3V. Question is that this...What do I need to do with the ECU to run this setup in either of those 2 F150's? It was supposed to have the ECU with it, but long story short, I now must either have mine reprogrammed if possible or an ECU from a 2010 and then issues with the security system and all that entails. Anybody do these swaps before that can help me out? I have numbers from the engine & transmission if needed for the programming and if I need a certain ECU build. Thanks for looking and any advice in advance!
