Is there a wiring harness that will work with the 4.0 and still plug into the round plug on the 89 Bronco II?

I am installing a 4.0 from a 1994 Explorer into an 89 Bronco II. Or will I have to get dirty with the cutting and splicing of the wiring to make it work? I have the computer ans some wiring from the 94 Explorer.

Thanks
