Assuming you have LH 2.2 (I'm not familiar with 700s), the ECT sensor wire is Pin 2 at the ECU.

Pin 13 goes to the Injector common, but I don't think it should read 12V unless the Fuel Relay is energized (shouldn't be unless cranking or running).

I would measure resistance from the ECU connector Pin 2 (unplugged), to be sure the wire is good from the sensor to the ECU.
