What?  You want to run the turbo auto box with the non-turbo auto box's TCU?  Why would you do that?  The non turbo box's TCU is not the right TCU.  You want to use the one in the Neo ECU.  So you need the Neo engine loom (which you probably have) and you want the other looms that connect the ECU/TCU to the tranny.  If you don't get the looms, then you're going to have to consult the wiring diagrams and build them from scratch, which does not sound like fun.
