2020 tacoma JBL system

Got a quick question...
I'm a new Tacoma owner so needless to say I will be visiting these pages quite a bit, seems most of you guys are awesome and know your sh**. I have one question and maybe someone can point me in the right direction. I'm going to retain my factory head unit, but plan on later changing out the factory amp (piece of junk) and upgrading the speakers. I plan on using the 541AP4TY13 PAC Amp Pro Amplifier Interface for 2018-2020 tacoma with the JBL system. As we all know the JBL system in these trucks are pretty bad to say the least. Anyway, my question....
This harness can only be used if your JBL system has a 10 pin & 28 pin connection on the back of the existing head unit. Can anyone confirm this is the case in these trucks?



Thank you in advance

 

I do not believe the 2020 JBL used those connectors at the radio.

just pull your head unit and look. Will take you 30 seconds

 

I just did... it indeed has the 10 pin and 28 pin connector on the back. Thank you
