Question about Ford E-150
I just replaced a 5.0L with a 5.8L engine in my 93 e-150. Kept the original transmission from the 5.0. My questions are #1 do I need to replace the powertrain control module? Do I, and how do I,need change the wiring around? I can't seem to find a wiring diagram that is very discriptive.
Well the wiring for both engines is essentially the same. The only real difference between the two engines is about an inch of block height and piston stroke. Wiring should not have to be changed at all. You should replace the PCM, a 5.8 may run, but it will not run properly on a 5.0 PCM. I believe you should find the computer itself behind the passenger side kick panel. 10 mm socket releases the harness connector from the PCM then just rock it back and pull up. you might have to jiggle it a bit, but the 10mm socket is the only tool you should need.
