I found it very funny that there is an internal board to extract PoE power

It uses normal Ethernet and barrel jack cables internally to connect to the main board

I was unable to find the "Ethernet Master Connector used on #ford's Gateway Module (#ecg2)

So I hacked up #teconnectivity's similar #gemnet connector to make it fit
the original GEMNet connector. it has a metal housing, and is just slightly too big to fit in Ford's connector. I cut away the metal housing with pliers. the hacked up connector with some heat shrink hiding the mess the hacked up connector successfully connected to a Ford Gateway Module PCB the hacked up connector (using the little plastic piece at the center, with the metal shielding of the connector cut away)
