How do you wire a stereo straight with no harness in a 2004 Pontiac Grand Am?
3 Answers
you have to trace the wires , you have to know which speaker is which, you'll have a wire with power all the time , another wire that has power only when the key is on, and the ground wire.

each speaker wire is a different color (by pairs) if one is gray+ the other will be gray with a black line -, & so on.
