Maybe it was disconnected for the same reason I did mine (although I unplugged the actuator, rather than disconnect the linkage): After I replaced the amplifier with a resoldered one (which didn't change anything) and installed another actuator, I could feel a vibration in the accelerator. Going back to the last thing I changed before it occurred, I unplugged the actuator and the vibration disappeared.
I am no further in figuring out why my cruise control still doesn't work, but at least I no longer have this nagging vibration under my right foot.
