I recently bought a 91 lx hatch that originally had a 2.3. The cars front suspension has been upgraded to the gt goodies. The previous owner did a 5.0 swap from an old crown Vic I think, its a non mass air 5.0 ho. I came across a few 96 explorer's with the gt40p's and such. I want to pull my current 5.0 ho and put the engine from one of the explorer's in my 91. My initial concern is do I pull the ecu from the exp, or pull one from a mass aired fox? When I pull the explorer engine ill be pulling the harness as well. Any guidance is greatly appreciated. Thanks in advance
