Does anyone happen to have handy the ECU pinout for the 97 SC300? The 97s had 3 O2 sensors and I need to figure out which set of pins to relocate for the aristo ECU. I'm pretty sure I'm using the plug for the sensor that was on the rear part of the header, Cyl 4,5 & 6. I know I'm not using the post cat sensor as that's in the cab of the car and the front sensor plug is long gone.

I can find pinouts for the aristo ECU no problem and for previous year / OBDI cars but the 97 has eluded me so far.

thanks!

 

PM Gerrb.....he may have it

 

On the following 1997 diagrams , you should find the pin numbers from the ECU for the three O2 sensors. Click on them if you want to enlarge them at photobucket so you see the numbers clearly.

 

Perfect thank you!
