PAC SWI-JACK in 03 Tahoe

[pjtoy2]

I have a double din installed in my tahoe but my touchscreen stopped working the other day. I bought a PAC steering wheel interface adapter to be able to still control the radio through the steering wheel controls but it told me that for my vehicle the wire is not behind the radio.

Does anybody know where the wire is located, what color it is, and the easiest way to access it? Thanks in advance
