A little more information ...

I don't believe the tuner can work as I've described above, at least not with my sled. The +12V pin on the 5x2 connector isn't connected to the empeg at all - it's wired directly to the Amp Remote line (the blue one) on the wiring adapter.



Is this the correct pinout for the 5x2 tuner connector? I stole this picture from pca's PCATS tuner manual, and added the text of what I think the lines are. In any case, there is no +12V on the tuner connector anywhere, and I'm pretty sure the tuner can't work in that case.
