Hi @FR-S2GT86,

Thanks for the link. I've read through it and have a better understanding of the blue wire differences, and how the 12v signal would usually be a signal for the amp to turn on.

Here is an image of my Sony headunit wiring:

The aftermarket harness I've gotten has a blue/white wire to provide the antenna its 12v signal, and I have soldered those two wires together. But this wire then branches back towards the OEM harness (harness C in your post).

The problem is that when I look at the back of the OEM harness pin, the blue wire is connecting to nothing. So I think its impossible for the AMP to get its signal to turn on. Do you know of another pin position of where the Amplifier 12v signal wire would be? Or is my best bet to open up where my stock AMP is and follow where its connecting?
