The EFIS can be updated via a USB port, which can also be used to record the flight parameters. The port is at the back of the EFIS, but a port can be installed in the panel using an extension cord. Before drilling the panel I make a test on some leftover angle.



This is where the left USB port will go.



And the right side.



Here is one of the connector strips, it's the one that will be used for the EIS sensors.
