16 Wrx Map Switching Fail safe

[16-WRX]

Hopefully someone can help me out.

I would like to wire up the orange wire from the Aux to switch maps upon failsafe. I will be using the TGV sensors. So if I remember correctly I will be using the blue wire the green harness. My question is where do I tap the orange wire into. Since the accessport now allows map switching I would like to try this method. Do you have an solutions to get this to work or how to wire it for the 16wrx? I see most people just use the waste gate Fail-Safe.

Hopefully someone can help!
