Aftermarket deck wiring issue

I have a 2014 tacoma with factory jbl in it. I got a pioneer avic 8200,maestro rr and TO1 wiring kit and going to keep stock jbl system for a bit. Got all wired up but the amp connector adapter that has low level to deck is where i have issues. One end of the adapter is sort of see thru white that I can plug into the maestro harness but the other connector being solid white I cant find where that need to connect. The 2 small green wire off that I can connect to the maestro harness no issue. Is that plug I am looking for buried in the dash?
Any help. Thank you

 

Figured it out. Maestro to1 harness does have correct vehicle side amp adapter connector for 2014 tacoma with factory jbl and nav. Had to have local car audio figure this out and a work around. Oh well ill be ripping the stock amp sub n speakers out soon enough

 

So did you not have nav?

 

I have nav. Its all been figured out for a while. I ended up taking out the factory amp/sub and speakers and adding an amp, sub and door speakers along with rewiring to all speakers
