Tracking down ECT issue with ohm and v readings 200 1992

The care dies from idle if you give it gas until it warms up. The codes say it is the ECT. I replaced the ECT sensor with a URO. No change.

I then back measured from terminal 13 to 5 and got 6.05 volts with the ignition switch on. With the connector unplugged from the ECU, I got 8,200 ohms between 13 and 5.

So does this point to digging into the wiring harness below the 2 and 3 intake manifold and looking for the cold joint on the ground (described by a post on the Brickboard), or looking elsewhere?

Any help would be greatly appreciated.
