1988 245 Coolant Temp Sensor mystery...which one? 200 1988

I looked about the forum until I lost patience. I suspect a bad coolant sensor for the ECU is giving me rich, fast running (900 RPM) idles. Here's the challenge: the forward sensor is for the gauge, single blade, and it works. The one behind it is the ECT, but it's a single blade as well?!!


All parts I can reference are the dual pin type. What gives? Do I convert?
If so, which pin will be the correct one, and will it run to spec?

Really odd. Thanks in advance.
Bill
