I finally figured it out and posting in case it will help someone else. My kit came with the white wire cut on both harness ends - the side that plugs into the main control unit and the side that plugs into the motor control plug:

It appears no one else has it cut on the motor control plug end but everyone has it cut in the main control unit end (where you have to pull the sleeve up to see it actually cut).
No video instructions or written had a setup like mine where it was cut at the motor control plug so I didn't know I had to connect it (I assumed if it was cut on the other end, what's the point of connecting it here). Speaking w/ Hans, he told me I had to connect it. Since my setup seemed unique, I assumed I had to connect it on the main control unit end - right? What's the point of connecting it here only to have a break in the line on the other end - DEAD Wrong. The minute I re-disrupted that white wire connection at the control unit end, voila - the kick sensor worked.
Go figure!
