Are you jamming down on the wheel buttons? They sometimes need quite a bit of pressure to engage
Yep.

Sure, there's that. But please explain to me why upon replacing the original VSS, the cruise work and the second time I replaced it did not. Nothing different other than the manufacturer, two new parts, one two wire plug, one bolt. First time, pulled out of the driveway got to 50mph and engaged the CC and it checked all functions and it worked as designed. Other than a increase in the speedometer fluctuation, it was fine. Five minutes later, it went totally up. We finished the intended errands and returned home. The truck sat for a week or so then I put the Motorcraft VSS in and repeated the same drive, engaging the CC at 50mph and nada...
Pull out your glove box.
The ABS control box is behind that. Unplug that box.
Now go for another drive and check the speedo.
Somehow I missed this! Thanks, I'll give it a shot in the morning.Pull out your glove box.

Did it, did it, and did it. No change...Yes. Yes. And yes.
Definitely interested in what you figure out. I had the OD light flashing and speedo jumping. I didn’t know better and ended up blowing the front seal out of the freshly rebuild trans so Pulled it out again and had it rebuild (rechecked) again. Then started tracking down the problem. Replaced the wiring connector going into the trans control module (I believe) because the lock clip was broke off and trans guy thought it might be sliding up and partially unplugging causing the problem. that didn’t fix it. Replaced the speed sensor and FIPL sensor, still didn’t fix it. Trans guy recommended possibly the speedometer jumping causing trans to shuttle shift back and forth, so switched that out on the cluster. Still didn’t fix it. I eventually ended up finding a wire in the speed sensor harness about midway between the axle and frame that was had about 2 strands of wire keeping it connected. I fixed that and it took care of the OD light, but still have the bouncing speedo.
yes it is an O’reilly’s bought speed sensor so might eventually try an OEM one to see if that works after reading this about aftermarket ones causing the bouncing.
my cruise doesn’t work either. Not sure if it’s necessarily related though
Did you try did you try unplugging ABS box behind the glove compartment?
