Radio Install Question with Crux SWRTY-61J

[PowerPro25]

Does anyone know which wiring harness a 2003 Toyota 4Runner with JBL and RDS is? Is it the TY-A or the TY-B. I called crutchfield and they told me I would have to pull it apart to see, but I feel like I should be able to know somehow which one it uses without pulling it out.

Another question, I am assuming the purple and green wires (rear left and rear right) for the headunit are not used with the Crux because it does not show this with the SWC harness.
