I plugged in the PA-12 last week and confirmed that it will work well with 4v pre-outs by using an old Pioneer deck and a spare battery.




I had some issues because there was already an iPod adapter installed up front with the MID and I had to remove it before the CD/SAT input would be recognized by the MID.
If you don't have Sat or CD changer it is a little tricky finding the plugs. They are there but they are tied up tight to the harness with zipties.



Found them!



With the PA-12 you connect the smaller 3-pin connector regardless, the 6pin is connected in non-DSP systems and the digital cable is connected with the DSP systems.
