+12V constant should be blue with a yellow stripe

I think there is a "co0nstant" source in the fuse box behind the coin holder compartment near the driver's left knee. Check those terminals to ground with a volt meter. A line right to the battery is always good.

no need to go through all of that. Just pull the stereo, connect the yellow wire from the stereo to the blue with yellow stripe wire comming from the factory wire harness. That wire is the +12v constant for the stereo.
