your car is a 95, i've tried to research why some 95's have the 96 wiring harnesses, and it doesn't matter about the production date whether it's an early model or a late model some of em have one harness and some of em have the other. i was thinking possibly it could be where they were assembled but that's as far as i went. before i wired a motor into anyone's s14 i'd always check the f4 pinout functions (well you kind of have to anyways to wire the new motor in there).
anywho, you're not the first one, if you're unsure on what you're doing just bring it by the shop or call and i'll see what i can do, since you're in GA
