Which yellow wire are you referring to as not having power? If it is the one on the ballast resistor terminal where the orange wire from OD relay connects, that should have power whenever the key is in the right or run position. The wire is fed directly from the IGN terminal of the ign switch via a splice connection. One spliced wire goes to the resistor and the other spliced in wire to the fuse block for the instrument cluster and maybe a couple of other items.

If it is the yellow wire that went to the old relay TH SW terminal, that would be ground side with ground supplied thru the governor when car reaches speed. If the inline connectors are good that only leaves the kickdown sw and the governor itself as the issue.

In testing the yellow ground wire side, you should be able to put one voltmeter lead on ground, and use the other lead to check each side of every terminal and connector in the yellow wire string. As long as the governor contact is not closed and connected to ground and voltage from the orange wire is feeding thru the relay coil, voltage should be able to be measured at every connection point down to the governor. As soon as the governor supplies a ground thru its contacts then the voltage in the string will go away and relay would energize. If there is voltage on one side of something but not the other that item is the problem.

On the governor itself, make sure all the mounting screws are tight. One of those that holds the plastic bottom to the body must be making good contact with the metal strap on the plastic bottom. That screw and strap is what supplies ground to the contacts.
