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!!!!!!

 

eh,,



looks like you are going to be riding the red rocket tomorrow man.

I can look up whatever I can.,...

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.

 

its karmen

 

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?

 

gah, i hate to bring this up but im really stuck. I have been searching for an hour and cant find crap. I need to know how to install the SC300 OBD1 1992 I just cant figure it out...im trying to do some research for the person installing it for me

 

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

 

yea its a SFAC 2 but that tech doc didnt work for me...idk y...I just need a write up I guess?

 

When I get back onto my computer later tonight, I'll take a look and tell you what it says. Or if someone else wants to do it before then......
