New Water/Methanol Injection Failsafe from AEM

For AEM they make a Meth kit, and a Fail Safe kit. You can have one or both, but they are not exclusive to each other.
It really was not that hard at all to setup. Just read the instructions and figure out where you want the failsafe wire to go, and if you want to use a high side or a low side input.
I love the config software. I dont have to deal with some complex set of buttons and working your way through 4digit led read out. Just plug in the laptop set it up and go.

The failsafe controller is in the gauge its self. You could simply tuck the gauge away under the dash and never see it again. You can also use the outputs to lite up warning lights on your dash.
So to answer you question, yes you can just tuck the gauge out of the way and not worry about it.

Hello Meth Heads!
Has anyone actually installed one of these on a stock ECU and got the MAP switching + failsafe to work?
I got one of these along with the new Injector Duty based progressive controllers and got stuck on the wiring. Maybe somebody could help shed some light... I think I'd like to use the ICS to enable the meth map, have the ICS lamp illuminate to tell me it's on, and in case failure is detected by the Failsafe hit the ADC_0F.
1. If using the ICS to switch the maps, is there a handy switched source to send +12v to arm the AEM controller? (ARM SWITCH (Yellow) in the big diagram below)
Jaime's cable diagram here doesn't cover this use case:
2. Assuming there's a +12v from the ECU that can be used to ARM the AEM, would it be best to clone Jaime's ADC resistor & zener network to provide 4.7v to the ADC? Could the source be the +12v for the ICS cluster lamp?
3. Now that the ADC is powered with the same +12v provided by the meth MAP, how does the failsafe ground it out without pulling too much current through the ECU? Maybe it would happen fast enough that no damage occurs?
Any clarification would be great.
Thanks!

There's an old thread, https://www.evolutionm.net/forums/wa...il-safe-q.html were someone recommended snow performance solenoid so as soon as it detects an error cut's boost. I don't know if this is working but sounds good, even thought I don't really understand it completely. Like, I already have a grimspeed solenoid. Can I connect my AEM kit on this solenoid (grimspeed), or do I have to add another like this ? >>> http://www.snowperformance.net/product.php?pk=14
