- Using a fuse puller or a pair of pliers, carefully remove the identified fuse.
- Using a multimeter set to DC voltage, touch the positive (red) probe to the metal contact on the removed fuse and the negative (black) probe to a known ground point.
- If the multimeter reads voltage, the fuse is the accessory wire. If not, try another fuse until voltage is detected.
How to Find Accessory Wire in a Car
When it comes to installing electronic devices in your car, it’s crucial to have a reliable power source. One of the most common power sources used is the accessory wire. The accessory wire provides power when the ignition is turned on, allowing your devices to function properly. In this guide, we will walk you through the step-by-step process of finding the accessory wire in your car.
Step 1: Gather the necessary tools
Before you begin, make sure you have the following tools at your disposal:
- Wire strippers
- Electrical tape
- Insulated connectors
Having these tools handy will make the process much easier and help ensure a successful installation.
Step 2: Locate the fuse box
The next step is to locate the fuse box in your car. The fuse box is usually located under the dashboard on the driver’s side or in the engine compartment. Refer to your car’s manual if you’re having trouble finding it.
Once you’ve located the fuse box, open it and look for a fuse labeled “ACC” or “Accessory.” This fuse is connected to the accessory wire and will provide the power you need.
Step 3: Test the wire
Now that you’ve identified the fuse connected to the accessory wire, it’s time to test it using a multimeter. Set the multimeter to the DC voltage setting and connect the positive lead to a known ground, such as a metal surface in your car.
With the ignition turned off, insert the negative lead of the multimeter into the slot of the ACC or Accessory fuse. Turn the ignition on and check the multimeter for a voltage reading. If you get a voltage reading, it means you’ve found the accessory wire.
Step 4: Make the necessary connections
Once you’ve confirmed the accessory wire, it’s time to make the necessary connections for your electronic device. Use wire strippers to strip a small section of the accessory wire and your device’s power wire. Twist the exposed ends together and secure them with an insulated connector.
After making the connections, use electrical tape to wrap the exposed wires for added protection. Ensure that the connections are secure and won’t come loose while driving.
Step 5: Test the device
With the connections made, it’s time to test your device. Turn the ignition on and check if the device powers up. If everything works as expected, congratulations! You have successfully found and connected the accessory wire in your car.
If the device doesn’t power up, double-check your connections and make sure they are properly secured. Also, ensure that the fuse you identified earlier is the correct one for the accessory wire.
