coupe. The harness also changed to eliminate 12v at the injectors when the key is off. There probably other changes in the harness.
As far as extra work for the older engine I am not sure, but I wouldn't accept the older model in your 95 as Fast300 notes. Secondly you should not accept the older style injectors because they and not as good as the new style injectors and have been noted to be failing due to elhanol fuel and other reasons.
