By the way, I might have gotten it backwards, what I just said about the wires. I was going from memory regarding which was which (pure-blue vs. blue-white) when I made that post. In any case, I clearly remember checking the instructions and soldering the one that the instructions said was "amp trigger" to the harness, and later discovering that I needed to also solder the one that the instructions said was "power antenna" to the harness.
