The fuel injector harness grounds to one of the bolts that hold the fuel rail in place (this is true for all of the intake solutions). On the back corner of the 2-piece intake there should be a standard ground strap from one of the bolts that hold the 2-pieces together to the firewall. This is the same basic strap that is used on all of the various intake types.
When you're under boost, the injectors are drawing a lot of current because they are being held open longer. The ground straps help provide a more direct path to ground rather than the sensor ground wires, which are not rated for that much current.
