I installed an Infinity basslink subwoofer that sounds great.
I used the line in side for best quality.
It has an odd effect when you change channels because the amp mutes and the sub doesn't.
I will share the wire color codes for the JBL Harman/Becker oem amp.
It is located under the jack compartment. It is labeled 86100-0W050 LEATHER
I opened the the amp and found these pins labeled on the pcb
I am not sure what some of them are, but identified most.
14 pin input connector in order left to right viewed wire side
Top Row:
RF=WHITE...LF=BLACK...BEFR?=BLUE...N/C...CC?=GREEN...AMP ON=PINK
Bottom Row:
RB=GREEN...LB=RED...MUTE=BROWN...SIGNAL GROUND=YELLOW...N/Cx4
The 16 pin output connector same view.
All wires on this connector have silver dots on them.
Top Row:
B+=Red w/Yellow stripe

Looks like Toyota wanted to confuse things by duplicating colors.
Someone might know what the other pins are?
The next mod is
