The short story is that since both the gyro and the accelerometer outputs an analog voltage, any connection made is extremely susceptible to electromagnetic interference, especially if the sensor is placed near a motor or solenoid. Additional connectors mean more points of weakness for the signal to deteriorate. A direct soldered connection is a more robust way to connect a wire to a pad than through an additional connector.

On a side note, if the interference gets too bad, you can always shield and ground the cable - doing that on an especially bad signal line can clean things up a little.

I love to take things apart. The fact that they work better when I put them back together it just a bonus.
