Identifying pins on ECU connector? Coolant temperature sensor check... 700 1992

1992 745 185K Rex Regina

Check engine light is on and the code is 1-2-3 (Fault in signal to/from coolant temperature sensor)

This car has been sitting for three years with a blown headgasket and a bad transmission. I installed a replacement head and would like to move on to the transmission replacement. I would like to do a pin test at the ECU connector to begin figuring out the 1-2-3 code.

This car has the Volvo 3531658 ECU and when I removed the connector I expected to see numbers identifying the pins either on the connector or the ECU but there aren't any.

Bentley's shows the coolant temperature sensor pin to be #13 on the LH2.4 and 3.1 systems.

Can someone give me the coolant temperature pin number and tell me how to locate it on the connector of this Rex Regina car? Thanks.
