Bruce Nunnally Posted May 31, 2009 Report Share Posted May 31, 2009 93-95 used OBD 1 computers (ECM/PCM). 96 started the OBDII computers. 2000 Was the major redesign of the engine. I would focus on 93-95 L37 engines as your target choices. Re-use the computer from your current engine.

Ranger Posted June 1, 2009 Report Share Posted June 1, 2009 '93 & '94 are the same. '95 used a different intake manifold and may use a different wiring harness. Link to comment Share on other sites More sharing options...
