Reset switch 3E board for TPA3255

Hi all, would anyone know how to wire up the reset switch from the 12v output to use as on/off(standby) on the 3E board for the amp by putting reset into low/high. I'm very much a beginner trying to build an amp and would like to use the reset as my on/standby rather than surging current through the power supply/amp every time I turn it off and on. Hopefully the diagram will have uploaded LED and RESET.JPG Thanks for any help.
