95 is OBDI 96 is OBDII. There were a number of significant changes between these 2 years when it comes to the engine. Sorry I don't have anything specific for you but the DIC should get RPM information from the PCM I believe...

Why was the engine changed?. You need the controls and sensors on the 96 intake manifold and throttle body change only if there is NO debris fron the old engine in the manifold !!.other wise replace with a clean one to prevent damage to the replacement engine sts96

Change to the 96 Intake manifold with the 96 throttle body with all the 96 sensors AND controls should do the trick for you. sts96

I think you're going to need a '95 PCM and wiring harness as well.
