Well I have it all hooked up but it only reads --- in the digital readout and full rich on the sweeping part.

I have the red wire tapped into the radio power and used a body ground.

I capped the blue and white wires but I found a link on tuners saying
-WHITE(Analog Output) Connects to any auxiliary unit with a 0-5v input.

what the hell is that? What is a 0-5 v input? is that my whole problem?

thanks fellas
