Boost controller back feeding

Hi im running storm x on my SR20. Im in the testing and setup stages of my harness build and when i power up the harness im using a ignition trip relay that feeds power from the starter B terminal to the rest of the engine harness. When i cycle the key to ON, everything powers up as it should, when i cycle the key off the relay doesn’t shut off. I have narrowed it down to the boost controller, everything works as it should if the boost controller is unplugged. I have the boost controller wired 12v and ground (orange & black from link flying lead) the orange & black wire is also showing 12v. I checked the pins at the ECU and its in the correct location. Is there a setting on PC link that i need to change for orange and black (Aux 1) to be ground not positive or is that orange wire supposed to be hot and i need to supply it ground?

The trip side of the relay is ign power from the key.

Something is not wired as you believe.  The only way the boost solenoid could cause a back feed was if it still has 12V to the other side of it after the ignition has switched off.  This supply relay is staying alive for some reason.
