I'm having a hard time finding a wiring diagram or harness adapter to tap my sub amp into. 2016 Highlander XLE without the upgraded JBL audio. Can anyone help me figure out where I tap the subwoofer amp into the stock head unit for power trigger and audio source? A wiring harness adapter would be cool also but not necessary if I can determine where to tap into on the stock radio harness. I'd be super appreciative.

Likely you will need access to a shop service manual to get detailed schematics on premium systems.  That info is not well published or shared. 

There are some online shop manual services were you can pay for a day of access (or 3 days) and download all of the diagrams you need.
