FYI: ALL 95 Maximas are OBD-II
There is no such thing as a OBD-I 4th gen Maxima. I've confirmed this on three 1995 Maximas with my OBD Scan (OBD-II) scanner. The 95s have their OBD-II connector located above the ECU on the passenger side of the console. The 96+ appear to have the connectors all located under the steering column.

Yeah I've never bought into the idea that like 2 months into the model year Nissan decided to change from OBD-1 to OBD-2. I'm willing to bet someone will chime in with "I know for a fact my car is OBD-I" or "I know for a fact that ____'s car is OBD-I"

Not sure if this means anything, in order to get to my connector. You would need to pull the fuse cover under on the drivers side console, just near the hood release. The connector unit is located to the right of the fuse box. That is where I saw them plugged the OBD scanner in... Unless this connectot means something else???

So hold up if they can check your cars computer with a little diagnostic port, it means that your car is OBD-II? If it is then I'm OBD-II because I had it checked at the dealer that way.
Mine has a plug right next to the Fuses too.

i have a 95 and recently had to take emissions.
when i pulled in, they ran is and ran it on the dyno instead of doing the plug test. i asked why they did that and they told me that since my car was OBD-I, they had to run it.

I am waiting on Ben to chime in, we had a discussion last weekend on why the differences detween my '96 and his '95. This was sparked when I noticed he did not have the same clutter under his hood that I had under mine.

The connector is white and has two rows of pins. On the 95s I've scanned, the connector sits just above the kick panel that covers the ECU on the passenger side. The connector tucked up close to the console and in a vertical position. You can't see it unless you get on your hands and kness and turn your head. On my late build 96, the connector is located under the steering column near the dash fuse panel.
The 95s I've scanned were all early build 95s therefore it's safe to assume all 95s are OBD-II. The 95s all had codes stored which means if they had OBD-II specific codes stored, then they're OBD-II ECUs. The only thing I notice that different with the 95s is that they don't all the EGR gear on top of the intake manifold and that they don't display the pressure (Hg) on the OBD scan.
Per OBD-II, all connectors must be within 3 feet of the steering wheel, in the passenger compartment, and easy to get to within 30 seconds.

I called another dealer today and they said to see if I had OBD-II to go and check the emissions sticked under the hood. I went to check and I dont see anything about OBD...He said it would say either "OBD-I" or "OBD-II" Anyone know about that?

Yeps, ive been saying this for years. All 4th gens are OBDII. I have never seen any 95 Max OBDI. Even early production ones like 6/94 are still OBDII. The 1995 Nissan Factory Service manual says its OBDII. There aint no such thing as an Early version FSM for OBDI Maximas.

Like others have said, it would have been stupid for Nissan to waste money and make one model year OBD-I and then following year upgrade the car to OBD-II. Think of all the money and time they would have wasted.

Mine better be. I couldn't find the sticker but I could find the connection point on the pass side behind the console.
I'm expecting UPS to deliver a present for me today! (http://www.digimoto.com) If it wasn't OBD-II I would be f***ed.
If anyone is having trouble finding this port, stick your head under the glovebox with your nose pointed towards the steering wheel. You should see it if you are looking at a 95. It's basically a white trapezoid.
I agree with Dave... call it wishful thinking if you want, but I really don't think Nissan would run two different interface protocols during the a32 production. I have not read this entire thread but has anyone called up a Nissan dealer service desk and asked this question?

Well when I went to the dyno yesterday the morons there said, "This car is OBD-I so we can't clear the codes." It was my first time and I didn't want to risk looking like a retard so I didn't argue. When I go back after my next mod I'll show 'em the plug. BTW, is this a decent pull for what I have? Nobody is responding in the dyno disscusion forum.

Let me be the noob here and ask what the hell this is going to do for me. Is it just going to let me pull codes? Don't get me wrong, that sounds nice and I'll be getting the setup as soon as I can, but what else is this information going to do for me.

Ok, I've got a question...
I'm not doubting that the 95 is OBD-II, but every single 4th gen i've ever touched has the ECU plug right next to the fuse box. I've noticed the one on the passenger side on mine and I've always been curious to what it is and I've had the Consult, Consult II, and NProbe (great Consult alternative that costs MUCH less) and they have all been plugged into the connector at the fuse box and as far as I can tell they've all read like and OBD-I ECU. Question is, what is the difference between the two plugs and if it's OBD-II, why would the two plugs read different?
I could be completely wrong and the one next to the fuse box reads everything except for the few sensors that don't show up that Dave mention earlier in this thread...
me confused...

whats he talking about. mines next to the fuse cover as well.

Wasn't it a law that all cars 96 and up had to be obdII compliant? Some cars built in 95 were and weren't obviously. In my city, emissions is done by scanner on 96up cars, and by dyno on 95 and under cars. Not necessarily meaning that all obdII cars get plugged in, some actually get dynoed and the classacts that run the tests think everything under 96 is obdI.
