The Painless Performance Perfect Engine Management System for the 4.0L engine would make for a clean, tidy package with its minimalist wiring harness and tiny Delphi MEFI 4 computer. However, the harness is built around the later '97-'99 type sensors and our older '92 engine would have required a considerable amount of retrofitting. It pained us to send it back (no pun intended) but it's a system better suited to a much nicer buildup than we are working on.
