I understand what you're saying. I didn't see many specifically going into detail on JBL Premium speakers and what adapters. I really want to leave the adapters and harnesses alone. There's a lot of info on the Entune non-JBL and standard speakers. Most of the JBL Premium Speakers are just ripped out and rewired with a new amp. I just wanted to upgrade the speakers themselves knowing there won't be huge improvements. But aiming for slight improvements at a fraction of the cost. Just want to find the connectors. I did start a thread over there and listed my findings of connectors and haven't received any input. I'm guessing people just tossed the JBL Speakers aside or they cut and soldered the factory wiring. Just trying to avoid that. I'll keep digging. See if I can find better pictures and try to match it up. TW is blocked where I'm at at the moment. I also assumed if I could figure out the exact model numbers, I could share them with the community so everyone knew for sure going forward.If you haven't done so already, check over at Tacoma World:
There are several threads there about speaker swaps on the 2016 - 2019 generation, with a lot of details on the wiring and custom-making harnesses.
