Its' the way the relay is wired: to the BLUE Amp On wire. To do Auto EQ, you need to turn Resource OFF, which turns the relay OFF. You need to provide 12V to the BLUE wire going into the relay when doing the Auto EQ. I used cheater clips (alligator clips with points that bite throught the wire layer without damaging it) to turn on the relay while on Resource OFF. The Auto EQ is available, not greyed out.
