I've read the so called DIY for this but it is very vague. I understand that you need to find the output from the radio, left and right, which I believe is pin 1 white and pin 7 red, I also understand that you need to "loop" these directly back to the radio and bypass the eq unit, what I can't find is the wire colors of the "input" back into the radio from the eq. Anyone have a diagram for this or know the wiring colors?
