is the set up for the gt and gts premium sound system the same like the wire colors, location of things etc. and can i use that Scosche TA03 for my gt as well?

If you have the "Premium Sound" I believe they are the same JBL speaker set up. Thus as far as I know wire colors are the same, etc. I don't know that toyota would spend lots of money to put completely different wiring systems in two relatively similar cars.
