I need Help on Idle Control

I have a problem regarding the IDLE control connection. Do anyone knows where I can find a diagram showing the idle control connector and it's terminal connections.

The connector is 3 wire : Red/Black - Yellow/Black - Brown


I need this to connect it to the standalone ecu.

Please note that I am referring to the 99up yaris idle control where the throttle is by cable and not electronic.

Thanks

Thanks for the pdf but I am still not understanding the diagram exactly.

If you can help me identify which of the wires are positive and neutral and signal would be good

I only found this related ( see attachment)


Thanks

From the PDF:

Brown is ground
Red/black is the signal
Yellow/Black is +12

Thanks CTScott I appreciate your help

From where can I get the full manual of this?

Or at least do you have the page where it mention duty cycle and frequency or any related information on the Idle control signal specification?
