I have been largely unsuccessful at locating any wiring diagram or pinouts for the output (cables going from TAU to speakers) and has caused a roadblock in my installation. I am using 9-wire from a pioneer amplifier to power new front and rear door speakers. My plan was to splice into the cables around the TAU to amplify the signal going to the speakers without wiring the amp through each door. I will provide pictures to explain what I am looking for. Please help figure out which wires go to the speakers on the smaller of the 2 plastic wire harnesses. I am looking to forego a PAC adapter which I have seen similar threads for.
