Thanks for trying to help me mate. I tried it tonight with the failsafe solenoid with 12V IGN on one side and ground on the other side. No 4wd. Just spinning the rear. Even when setting the controller to manual mode and full locked 4wd. I might try keep all the factory wiring in place and just have the FullRace system control the ETS solenoid. However, I would much prefer to hardwire all the system so that I can ditch the Attesa ECU. -
Well, it has to be. Yes, and, they are saying "This failsafe must be disabled" (My emphasis). And they are saying exactly how to do that.... "Giving the failsafe a switched +12V constant signal will keep the solenoid closed/disabled". I interpret that to mean that "any time the car is running, you want 12V permanently on the solenoid". Ie, power it to close it when the car is running. Have the power switched off when the car is not running.

I don’t think it is ground. From factory it has 12v switched to one side of the ETS solenoid and the failsafe solenoid. Then the factory ets ecu has a pinout to send voltage to the otherside of the solenoids. I can see the ETS solenoid ranges from 0-3.3V to control the pressure to the transfer case. Im just not sure what voltage goes to the failsafe. I’m wanting to hardware these solenoids to avoid using the factory computer. I’ll link the factory R33 wiring here.
