How to Locate the Remote Wire for Car Stereos

The remote wire for a car stereo is used to provide a low-level 12-volt signal to an external audio/video component, such as an LCD screen or audio amplifier. When you power on your car stereo, the external component that has a remote wire connected to it will power on as well. Most aftermarket car stereos feature a remote turn-on lead within its main wiring harness. Stock vehicle radios typically do not have a remote wire option.

Things you need

  • Vehicle-specific general repair manual

  1. 1

    Remove your aftermarket radio from the vehicle if it is already installed. Consult a repair manual specific to your vehicle in order to perform this task. If your car stereo features locking tabs on the right and left side of the chassis, pop off the stereo’s trim bezel, insert the flat metal “keys” that came with your stereo into the small slots on the sides, and pull out the radio. Use the this method instead of disassembling your vehicle’s dashboard.

  2. 2

    Locate the remote wire on your aftermarket car stereo by referring to the product’s installation diagrams. Certain aftermarket car stereo manufacturers will provide a wiring diagram sticker on the radio chassis for reference while others may provide identifying tags to distinguish the wires. Commonly, the remote turn-on lead on an aftermarket car stereo will be blue in colour.

  3. 3

    If your car stereo does not feature a remote wire you can use for your external components, navigate to the resource below in order to find the specific “switched” or “12-volt ignition” wire your stereo uses. You will be able to choose from your vehicle's specific make in order to find the correct wire to use as a substitute remote turn-on lead for your external components. Using this method will ensure that your external audio/video components power off when your vehicle’s ignition is in the “OFF” position.
