Hi does anyone know or have a picture of the stereo wire diagram for an 02 ga? I need to figure out what wire is the accessory line. I installed a sub for a friend of mine and right now it'* running off the brown wire which comes on when the car is in the on position. But we found out today that, that wire is the head light wire. So his lights have to be on for the amp to work.

(stupid pontiac/gm running dumb things through the stereo to make life harder)

This belongs in the lounge because it'* not Bonnie related.

Check out gaownersclub.com . They've helped me out with my wife'* 04.

ok, they only have 2003 and up and everything below 2001. They don't have 2002. Even the guy at the bottom of the thread asked about the 02'*

I'm not sure if this will help you or not. You'll probably have to play with it a little. Here is an excerpt from the Description & Operation - Amplifier:

When the radio is turned on, the radio sends a voltage signal to the audio amplifier via the amplifier control circuit. The gain control signal circuit allows the radio to recognize that an amplifier is present. Once the radio detects the amplifier, the radio will output low level audio signals to the amplifier. With the amplifier enabled, the signal that drives the speaker is now amplified.

These are pins possibly applicable to what you're looking for:

A7 - LT GRN - Remote Radio Control Signal (Pontiac)
B3 - DK GRN - Amplifier Control
B6 - PPL - Gain Control Signal
