Jayce, you might look at the following link on my friends chassis. A little insight into the internals of the speed dial. Yes, there are two connections external to it. One is the extension of the muting switch going to the center tap of the volume control. It starts at the very base when the speed dial is removed and looking down the shaft. There is a circle down there that is much like the circle on the muting ring that slides down the shaft and has a tab that sticks up on the part of the yoke assembly you have, into an insulated slot on the yoke. If that makes sense. In fact, without the yoke assembly on, that tab that sticks up to go into it, if you touch it with your finger and make certain it is pushed back down the shaft, you will get a hum like touching the center tap of the volume control. A nice hum. If you put a alligator clip set up on the tab and connect the other end to the ground, you will mute the radio. Your yoke will do the same thing when you have the clip on the washer lined up in that nice recess and push the yoke down like pushing down for a preset button. That will bend that little clip off the washer to ground out on the contact to ground on the the insulated recess. I was missing the lever for the yoke assembly as you are. I was lucky to find someone who had one and also other things like the washers etc. It was a trip. If you need some pictures let me know. Mine is still apart, but going back together again soon.
Here is a link to my problems and more.
