Your sig says your car is a 2003. You need to run the red wire to the ignition switch wire (it should be a brown wire). 2003 and up cars need the radio wired to a switched constant unless you're using the Scosche adapter with the dinging thing.
You also have to connect the yellow wire to the harness. It's the battery constant. The Black one is ground. The harness should have it, if not then just look for a metal connection in the radio area. Pink, I think it's the power antenna cable. You don't need it.
