So the wiring harness adapter I'm using is a Metra copy more or less that I bought off eBay. So it's similar but different. But the wiring diagram for my 2007 is somewhat different than the ones in the Service Manuals that can be downloaded from the Forum. I'll attach a few documents for folks to review and hopefully you can steer me down the right path to get the OEM amplifier & subwoofers turned on.
