2006 Toyota Tundra Jbl Wiring Diagram

So in preparation of my stereo upgrade, I pulled out my factory JBL head unit to look at the wiring harnesses to see what I was dealing with. To my surprise, there were actually 2 wiring harnesses to the back of the stereo. One small, with 6 wires, and one larger, with 13 wires. So I am a bit.. I am looking to add a subwoofer to the stock non jbl with navigation entune unit (2019 crewmax). Does any body have the wiring schematic handy?.
