Need help figuring out a turbo timer problem

[Ziggy1647545504]

I'm working with a shop on a customer's car, a lightly modded 2004 WRX STi. We had this vehicle at a shop here in Cinci, and through the course of some unfortunate circumstances, had to do a lot of additional work to the front end of the vehicle. To make a long story short, the battery was disconnected, and for what ever reason, the turbo timer is not working properly. It is getting power to the timer itself, and the timer counts down, but the engine is now turning off with the ignition switch instead of continuing to run while the timer counts down. I'm trying to help out my shop here and hoping someone may have come across something similar. To my understanding, everything seems to be wired properly, and my shop had no reason to mess with anything relating to the timer unit, but maybe cut a wire? Dunno. Any ideas?
