Remeasured everything again for greater certainty... Test 17 show .001 volts for the key pins 35 to 9. I do not have any 9,20 or 22 pins on the connector, they are blanks. I then reseated the connector, did the procedure again, and this time got the 5 volts! The relay 204 definitely clicks when the fuse is inserted. The voltage from the black on the diagnostic connector to the engine block is .002 volts, so very low, but not zero, tried various engine and chassis points and got the same readings. Key off, the Resistance from terminal 31 of 204 relay to the middle black wire on 186 is 0.7 ohms, is this low enough? Hard to believe I finally got the 5 volts on the 35/9 pins after measuring so many times, removing and replacing the connector a number of times, but it is what it is. The mystery remaining seems to be the 204 relay clicking when the fuse is inserted while the key is in the engine on position.
