2016 Tahoe PPV no sound and wiring issues

[kenmarien]

Hello, I'm in washington and recently picked up an 2016 Tahoe from auction that was used by the California highway patrol. I have put in about 5k in it already fixing little issues. It looks like I will have to paint it because it has white doors and white roof, and the hood is faded so bad. One thing I realized was that the vehicle does not produces any sound, even the started up chime that comes on wherever you start the car, the radio turns on quite well but it looks like it's inoperable because it doesn't even display all the options on the screen to play with. Ac and everything works well. The turn signal lights work but they don't make any sound like a clicking sound that it's usually suppose to make. I go a stereo from the suburban to upgrade but realize that they harness is messed up from the police rewiring things in the vehicle. I can't seem to figure out what harness I can use to connect my new center console I got from a suburban which fits properly but just that it has the option of heated seats and my seats are not heated seats, I just want to be able to have the USB and the power plugs to work that's all. Does anyone know where I can buy and what type of harness I can use to connect the center console and also for the upgraded stereo from the suburban? My wiring is just so confusing with how the police had to rewire everything. See pictures attached. Where is the amplifier on thus thing located because I looked in the rear left corner of the trunk but it's nothing there.
