Going to attempt to put a 2006 engine in my '03 (6.0L) f250. 2003 engine is toast. Got the 2006 engine for a VERY good price with low mileage. I know the HEUI system is different. I was going to modify the wiring harness to reach the ICP sensor because of the different locations on the engines. What other things might i run into? Or is the swap even possible?
