Tricore cable is a genral cable which mainly designed to work DME and DDE. You can find a way to do the connection or you can use the special optional EGS cable for Autohex:

You need to power Autohex only. It will manage powering the EGS via the tricore cable.
After resetting the EGS, you always should do programming and coding after you mounted on vehicle.
