Default 08 WRX failsafe w/ HFS6 & GrimmSpeed EBCS

I'm using a GrimmSpeed 3-port EBCS and an HFS6. Would like to know the ideal way to utilize the failsafe on the HFS6.

Since this EBCS connects to factory harness and such, should I connect white and brown wires as I would with an OEM boost control?

Also, is this diagram of HFS3 wiring applicable with the HFS6 as well?

As for the failsafe yes, just consider the GS unit to be the same as the OE unit for hooking up the wiring.

The connector on the HFS-6 is yellow, but the red/green/brown/white are all used the same.
