I see others have posted similar msgs for different models and years. I'm in the middle of upgrading the factory radio. I have purchased a standard kenwood and trying to match wires. I pulled out my Haynes Manual and found a wiring diagram, but many of the wires don't match. I began testing the red wires with a multi meter to see what was providing the battery power and what was providing the ignition. Haven't found any wires that produce more that 1 Volt. The radio was working before I took it out, so I know something was giving it power. I'm checking the fuse next. Anyone had similar problems are know of better wiring info?
