Which wire is remote on 99 Chevy van stereo?

There isn't a single, universally designated "remote" wire color in a 1999 Chevy van stereo harness. The color of the remote turn-on wire varies depending on the manufacturer of the original radio and even sometimes the specific model of the van.

To find the remote wire, you'll need to:

1. Consult a wiring diagram: The best approach is to find a wiring diagram specific to your 1999 Chevy van's radio. These can sometimes be found online through forums dedicated to car audio or by searching for your van's year, make, and model plus "radio wiring diagram."

2. Use a multimeter: If you can't find a diagram, you can use a multimeter to test the wires at the radio harness connector. Turn the ignition on and test each wire individually for voltage. The remote wire will show a 12V signal only when the ignition is turned on. Be cautious when working with car electrical systems.

3. Look for a wire labeled "Remote," "Amp," or "Power Antenna": While the color isn't standardized, these labels sometimes appear on the wires themselves.

Without knowing the specific radio model in your van, it's impossible to give a definitive answer. Always consult a wiring diagram or use a multimeter to identify the correct wire safely.
