I also could not find anyone to install my yoke. Companies wouldn't install because the yoke was not purchased from them.
So, I did it myself to found it was easy.
First, I watched a ton of YouTube videos of people doing it. Became very familiar with the steps.
The only tool I did not have was a torque wrench which I borrowed from a neighbor. I let the tools sit on a table in the garage for a few days until I built up enough nerve to start.
The day arrived. I went into the garage and disconnected the 12V battery and the main battery and started. The yoke was installed and I have been happy ever since.
