Ok i have started hearing and reading about OBDII port which became compulsory in 96+ cars. My question is does my 1990 Celica "GTS" (actually its an Aus SX) have this port or something similar? I would love to be able to read realtime data off my ECU and be able to display the info on my laptop/PDA.

It's OBD I. There are adaptors made for every single manufacturer DLC on pre-OBD II vehicles. On Toyota's, the DLC is a little gray box with the word Diagnosis on top of it. And FYI, it's not live data. It actually takes a couple of seconds. The older the vehicle, the slower the computer.

On the Celica is located right in front of the main clutch cilinder (right hand side of the car behind the shock tower if standing in front of the car)

I just have some minimal wiring diagrams that are in th Haynes manual, its the US manual but they apply to the Aussie cars too. Let me know if theres something in particular you need and i'll scan it at work for you.

ODB-II started in the 96 celica's. Its possible that only the USDM has that option. i know JDM has something similar but a US scan tool will not work on it.
