Am trying to diag a tach signal loss to ip, now serial data loss. When comparing powertrain wiring between 5.7 and 7.4 . I noticed injectors #3 and #4 , pins b31 and b32 are swapped. Is this a misprint? Which is correct? I have a 5.7 ecu i am considering replacing my possibly failing pcm. Any thoughts?
