You have an MY2000 car, not a 2001. ;)

You are looking for pin 21 on connector B136 going into the ECU, which is the blue plug.

If you look at the back (wire side) of the plug, the numbering runs from top to bottom and right to left . So, pin 1 is at the top right of the plug, pin 32 at bottom left.

Pin 21 will be the third row down, third pin in from the right. From memory I think it might be a white wire, with a black stripe running down it, but don't quote me on that last bit! :)
