Hello
I have a 1999 Grand Prix i just purchased. and the entire electrical system has been rednecked up. well i am currently working on the radio and the previous owners cut the factory harness. (im replacing just because i like to have all the proper oem connectors and switches) i have found a wiring diagram for the radio
Grand Prix Wiring Diagram
but there are 3 wires i cant figure out what they go to . 2 forest green wires and one blue (look at the picture below) does anyone know what these wires go to ?
