Default 2001 2.5 RS wiring problems

I have the ECU pin out from North Ursulia. My pin out you read from the back of the plugs. What is:
B135 pin #12
B134 pin #12
B135 pin # 11

I have wires but the Diagram doesn't say any wires belong there. A little help please.

Thanks in advance

I've got a set of diagrams sourced by a shop here in Aus.
The only one of those 3 that is in my diagrams is:

B134 #12 : Radiator fan relay 2 control : A/C vehicles only.

On that generation of ECU it should be:

B135 #11 and #12: Select monitor signal

You could check and see if the colors are the same as at the diagnostic plugs under the dash to be sure.

I also have B134 #12 as the 2nd fan on a/c models.
