The 5.2 and 5.9 have the same harness, correct? I am planning on the swap myself and already have a '93 MP PCM. I'm just looking for an engine and harness.
Also, diesel would be a different harness, correct?
Sorry, one more thing. Would the harness be the same for automatic and manual tranny? Thanks.
I already have a '93 Mopar Perf PCM for a manual tranny. I think all I need is well besides the engine, the wiring harness and flywheel. I planned on getting a '93-'95 'cause I know they took away EGR and changed some other stuff with the computer in '96.
Does anyone know if I can use a wiring harness from an auto with my manual tranny?
