Where is the actual module ? Is it the one in the driver footwell or ?

Thank you!

Front left corner (facing the engine). Big 'ol plug.

This is from a '15 manual - not sure if '16 is different.

Hopefully, this wiring diagram will help.

23:23 shows the location of the ECU harness. Don't use the wire mentioned in the video as it's for the TPS wire used for the WMI failsafe.

EDIT: Added the PDF version of the diagram, which is clearer.

Thanks guys.

I emailed snow and they said you don't "need" the wire. The controller can read from boost pressure, fuel rail pressure or both. So it's fine with just boost pressure, but can provide a more accurate reading / better control if it has both.

Still - I'd like to use the wire / hook it up. Between the video and the wiring diagrams I should be able to find it this weekend.

Thanks again.

Just following up to see how your install went. Interested in seeing the results of using both fuel rail pressure and boost pressure for controller amount of fluid injected.
