I’m trying to install an aftermarket head unit in my 2014 Tahoe PPV.
I purchased a wiring harness from Amazon, and the Amazon wiring harnesses physically plugs into the factory wiring harness with no issue.

However, the accessory power wire from my head unit via the Amazon harness ends up going nowhere (Page C-65, pin 16). (Red dots on pages C-64 & C-65 indicated where wires appear on my factory harness. I am unsure of the accuracy of this diagram though as just I grabbed it from this forum).

The Amazon harness also does not connect to pins 6, 7, or 13 on the factory harness pictured on page C-64.

Did I buy the wrong wiring harness? Do I have something unique going on since it is a PPV? Will I need to find an alternate source of switched power?
Please help if you have any input on this. I’m about to throw in the towel!
