Measuring ECT Sensor at LH2.2 ECU 200

I have a 1985 Volvo 244 (LH 2.2) and would like to verify the engine coolant temperature (ECT) sensor resistance at the ECU. The Bentley book states that the ECT connects to pin 2 at the ECU. I can't seem to find a diagram showing which pin is pin 2.

It's the one with the blue wire.



Your ECU is the Jetronic box inside the car above the passenger's right foot.

Thanks! I was able to measure the ECT at ambient and it looks ok.
