* What are you trying to power? (e.g., headlights, radio, aftermarket accessory, etc.) Different circuits have different power feeds.
* Are you looking for a switched power source (only on when the ignition is on) or an unswitched power source (always on)? This is crucial for safety and preventing battery drain.
To help you find the correct power feed, you'll need to:
1. Consult your owner's manual: It may have a wiring diagram showing power sources for various components.
2. Use a wiring diagram: You can find these online (e.g., on sites like Haynes or Chilton) or at a parts store. These diagrams will show the color codes of the wires and where they connect.
3. Use a multimeter: This is the most reliable method. With a wiring diagram, you can test various wires with a multimeter to identify the correct power feed based on voltage. Be extremely cautious when working with car wiring and always disconnect the negative battery terminal before working.
Without knowing what you're trying to power, it's impossible to give a precise location. Providing more detail about your project will allow for a more helpful answer.
