I know this has been covered before and i have searched but i can't get the search function to work right. i need to know, color, pin #, and connector for the speed signal and rpm on a 97 st. According to the how to on the afc the rpm is the 11th pin black an yellow but it doesnt say what direction to count from. if you count the way most manuals do it the 11th pin isnt black and yellow.anything will help thanks in advance.

If you're looking at the face of the plug count from left to right. Also edo's celica isn't from the US. I'll have to look at the wiring diagram for the US. EDIT: You're right. The USDM wiring diagram shows IGF (Ignition Feedback) as pin #3 black / yellow. If you're needing the SPD wire from the ECU it is pin #9 on your 22 pin connector either green or orange. Also, I just noticed you've got a 97 (OBDII) that might make a difference. Not sure since I don't have the wiring diagrams for it.

 looking at this it says that pin 11 on connector E7 is the spd sensor and that pin 9 is for RSC IAC valve. i just tried both and neither of them work. so i dont know what up. -Aaron- -------------------- |

That's for a manual transmision car. Don't you have an automatic? The speed sensor should be on your 22pin connector. If you're looking at the back of the plug it will be on the top row third from the left. You shouldn't even have a 12 pin connector.
