axxess line output converter

 hi i just bought a Axxess ADCET2  line out conveter at best buy. it did not come with any wire diagram if anyone knows it has 2 gray  2 white 2 black 1 blue and 1 yellow.i believe the gray and white are speaker in, the blacks are grounds, the blue is power turn on and yellow is con.if anyone can help it would be appricated

that is exactly rightAdvanced

i work at best buy, and this is a new package for something that we used to sell, you hook yellow to constant power and the unit senses the signal from the speaker wires an in turn sends 12v out the blue wire. its so you dont have to run a remote wire to an acc source. but when we used to carry them i tried installing one and it never shut off. i went through all 3 we had in stock and they all did the same thing, i tried them in the car and on my test bench, and same problem. its what like $50, return it and get our $19 one and run the remote wire.
