I don't know anything about EEC-IV code readers that won't work on a '95, because I've never used a code reader. I've also never heard of a system in between EEC-IV and EEC-V. I do know that once, while driving to Idaho with my dad, his CEL came on in the middle of nowhere. Stopped and found a small piece of bailing wire on the side of the road, plugged it into the EEC-IV connector like on any EEC-IV vehicle, and counted the flashes of the CEL to get the codes. If all you need at this point is trouble codes, give it a try and see if it works.
