Hello guys, I am in need of some wiring help. P28 s300v2 ecu EBC PWM

I have devils own injection kit with progressive controller...

I have 6 wires left to be firgured out. I am trying to wire in the AEM water/fail safe. In the pictures it is first 2. The last 3 are for the devils own kit.

I need help on what the following wires will be hooked up to. Currently I had an aftermarket transducer to be able to adjust and swap maps and boost level when pressure in line drops. I am doing away with this. I had 2 wires one going to A24 and D4. To trigger maps.

The 6 wires 2 which either go to A24 and D4. Need to know what goes where in order to get this AEM fail safe fired up. Which wires go to the controller and where????

On the AEM failsafe

White?
Brown?
Yellow?
Blue?
Green?
Orange?

Orange goes to blue wire from controller ?
Yellow ECU Switch Failsafe Use for nitrous map ?
Brown ECU Sensor Ground ?
White ECU (Log the data) PR Pressure Voltage ?

Green Optional Boost-Safe ?
Blue goes to chassis Ground ?

D4 as switched to ground inputs
A24 ECU power ground

You should contact the manufacturers of these devices for assistance with how to wire them properly. There are various inputs and outputs on the ECU you can use and you must specify them in the software along with the conditions you want. You may need to also discuss this with your tuner.

How I see there needs to be a relay on either Blue low side or Yellow high side. So you can't use both to sense? And cut boost. If you can better direct me on which wires need to be hooked up.

So far I see it as:
White analog + D4
Brown wire analog - A24

Yellow Hi Side +12v ????? goes where
Blue Low Side - ???? goes where

Green Fluid Leve Sensor - Yellow on Devils on controller
Orange Injection Percentage - Blue on Devils on controller
