aasc300

I just purchased an Apexi safc-II and I am currently attempting to install it in my 1992 Lexus sc300.
I could not find a pinout for the sc300, so I tried using the 2JZGE pinout for the 93.5 + supra N/A but the pressure wire is non-existent. Can anyone tell me the correct wiring for this application or at very least whether this car is pressure, hotwire, flap, or Karman type sensor? My car wont run until I get this info and I need to get to work tomorrow. PLEASE HELP!!!!!!

Well, all the monitoring inputs were right, so I just disconnected the airflow interrupt for now. The car drives fine but the pinouts for the 92 sc300 would help me drastically.

You might want to try doing a search on SupraForums...

So the sc400 and sc300 are both karmen? Does anyone have the pinouts for this ecu and the safc-II?

Is this info the same for the OBD1 92 sc300?

nope but the wiring diagrams should be the same.

Are you saying the ECU pinouts are the same and this is a Karmen system?

I did the NEO on a 1jz and it was really straight forward. If you go to apex-i's website, there should be wiring diagrams. You have an SAFC-II correct?

EDIT: There is a link for a PDF on this page. The "Technical Documentation" link http://www.apexi-usa.com/product_ele...=202&pageNum=1
