I re-watched Mike's teardown video to find any missing information and found this:

Bear in mind that stream could be data going to the sensor- you'd need to insert a resistor inline to verify.

I connected it to the scope to see which is least significant bit (it changes all the time) and came to conclusion that the first word is 12bit long and the following are 14 bits long.

But when I put my finger in front of seek the values did not seem to change noticeably.

So as Mike said this cold be line going into the sensor. It is very had soldering wires to seek.
Just for a reference...
Vias are 0.5mm in diameter and often only 0.1mm apart. And traces are about 0.1mm thick. :-/O
