I want to hook up my unused voltage input on the S-AFC to the O2 sensor output, but I can't find the pin on the ECU for it...if anyone could tell me the pin # or wire color for the O2 pin on the ECU it'd be a great help. I searched all over here and supraforums but only came up with the pin/wire color for the GTE ECU...

Thanks in advance, Marshall

 

I might have it here www.lextreme.com/misc.htm

helpful diagram, but there's no listing for the O2 sensor...unless I missed it..?
thanks again, marshall

 

the O2 pin is 48, just like on the GTE ECU...

 

www.apex-i.com or something like that.. the us apex website has downloadable PDFs for the SAFC which include the us spec supra ecu wiring diagrams

 

yeah they have lots of good info there....but not the full wiring diagrams with information such as which pin is for the O2...

 

there are two o2 sensors, pins 47 and 48 are the ecu pinouts.
