You're clearly on the track of something important, but you are not 
there, you're only close. The trick is in narrowing it down. You'll 
have to keep trying the same trick, but you need to find that place 
that takes a minimum amount of pressure/force to cause the engine to 
stall.  

For some reason, I was not able to view the second video, but in the 
first video you're putting a lot of force on the loop of wire going 
to the pressure sensor. Wiggle the individual wires going into the 
pressure sensor connector.

Then work your way out along the harness, to the other connectors. 
Find the place that just takes a light touch in the right direction 
to kill the engine.

One thing to keep in mind is that sometimes you can get a wire that's 
broken INSIDE the insulation. This can happen anywhere along the 
wire, but it generally only happens with wire that has suffered a lot 
of flexing over a lot of time, so I don't think this applies to your 
"new" FI harness. But it could apply to the 2 wires coming from the 
FI power relay. To test for this, pull on each wire. If the conductor 
is broken that will disconnect it.

Another possibility is that a wire slipped forward or backwards just 
before a crimp was made. If forward, the inner crimp will be on 
insulation and the connection will be accidental and intermittent. If 
backwards, the bare part of the conductor may not be within the part 
of the connector that was crimped, and again the connection will be 
accidental and intermittent. Either way will respond to force in 
various directions.
