Would a engine wire harness from a 1996 jeep 4.0 be the same as a 1998 4.0 engine wire harness? I was thinking of putting this 1996 engine into a 98 but the problem is that The 98 has no engine and transmission, everything else though..

 

I believe at least the connectors for the injectors would be different style

 

the color codes will probably be different also

 

There were major changes from 96 to the 97 and up model years, I would say no.
