-EJ22T/25D
-25D intake manifold and throttle body
I'm in the middle of merging my harnesses and can't for the life of me find an answer to what I do with my TGV wiring since I am using a 25D throttle body and manifold. Any input is appreciated. Thanks in advance!

I've just been informed my setup will not work, but will not tell me why...Can someone clarify what the bottom line is please?

First explain in detail what you're trying to do.
You could have "hot wired" into the 25D ECU from a piggyback or a full standalone ECU.
The 22T & the 25D use the exact same crank/cam signal/trigger, & the same exact crank gears.
For example, if you put 25D heads on a 22T short block & pushed only 6psi into the chambers, the 25D ECU will run it all.
But you're not using the 25D ECU, that would be the WRX ECU connected to that hybrid harness so here is what's next.
The WRX harness & ECU need the WRX heads & crank gear or your wiring endeavor will be for nothing.
Get some WRX heads & crank gear on that 22T then continue...

Simply put.. If your using a MY02+ WRX ECU then go in with ECUflash or Rom Raider and tell it to ignore the TGV's just like all the guys who install the TGV deletes or MY01 JDM STi blanks.

.. Just ignore the wiring and tape it off to protect shorting.
