To find it:
1. Locate the underhood fuse box: This is usually a black plastic box located near the battery, often under the hood on the driver's side.
2. Open the fuse box cover: The cover should either have a diagram printed on it or a separate diagram should be stuck inside the cover or located in your owner's manual.
3. Consult the fuse box diagram: Look for the diagram that shows the location of relays. Find the one labeled "starter," "start," or sometimes just a symbol representing a starter motor. The diagram will show its location within the fuse box.
If you can't locate it using the diagram, a search online for "2001 Chevrolet Tracker 2.0L fuse box diagram" with images may help. You can also consult a repair manual for your specific vehicle year and engine.
