requirement yes, but some manufacturers started implementing it as early as 94. I think nissan was one of them, since the ecu's are swapable between 94-96
so is my 94 really obdI or obdII

you are obdII. Nissan was one of the first to impliment the obdii system. It wasn't required until 96 so the port is hidden under the glovebox.

I had the consult software and cable currently on my '94, prior I had the OBDII software and cable... Over all the Nissan Consult port is the way to go, less headaches and good support.

hey if im not mistaken your car is an OBDI because i have a 95 G20t and it is OBDI, so i would image that your car would be and OBDI not OBDII

inspection stations won't use the obdii port unless it is a 96+. They probably don't even know it is there.

They told you wrong. Your car is OBD- II. I don't know what you mean by safety inspection only. In NY the difference between OBD-I and II inspections is that the II are not run on the machine for emissions testing. All OBD-I have to have the crap beat out of them by running on the machine. OBD-II just get hooked up to a computer.

Well yours is the only one in the US then LOL...

Have a look under the glove box area there will be an OBD-II connector aswell as the Consult connector under the fuses. You'll also find a crank sensor on the front of the engine that isn't fitted to an OBD-I car (The red one on the right of these pics... http://www.brazosport.cc.tx.us/~lshadoff/turbo/drill.html )

Hmmm I always thought mine was OBD1 for some reason.

I think the port where you hook it up is right underneath the dash in the passenger side, correct?
