it is difficult to get an answer this way

The problem you have run into is one of multiple ground paths. To my thinking, the readings you are seeing are through the relay coil grounds of the distribution panel. The solenoid winding resistance is typically less than an ohm. The relay coil windings range from 50 ohms to 300 ohms. It is difficult to see anything convincingly with an inexpensive meter.

This test is with the ignition switch set to OFF:

One way to test the continuity of the wire through the harness is to reconnect the harness, remove the theft relay from its socket and disconnect the yellow wire from the starter solenoid (leave it disconnected!) Now take a 6V flashlight lantern battery, and connect a wire from its positive terminal to pin 2 of the relay socket(the direct path through the harness) and connect its negative terminal to car ground.
Measuring this independent 6 volt signal between the solenoid terminal and car ground is easier and verifies the wiring harness.
