It looks like a diagnostic port next to the fuse panel on my car, but the car is basicly diagnostosed onboard.

you know how you open the fuse cover and you see the fuses, but that is that plug for?

You know, I was changing a fuse this weekend and saw that port too. It didn't occur to me at the time that the computers codes are read by watching blinking lights on the module itself. Now I'm curious too.

actually, i saw it too and Im not really sure. I always assumed it was the OBDII or OBDI port, the Haynes manual doesnt mention it though. Anyone know?

***** That was for the optional dealer installed nitrous system! :D Actually, before OBD I, or OBD II, Nissan had a little beige plastic "5 Mode Checker Box", that could flash codes, moniter the O2 sensor, and make adjusting the throttle sensor easier. Only dealers have this box, but I guess you could get one from the supplier of all Nissan tools, Kent Moore. They were really nice to have, to diagnose drivability problems.
