I got a 1999 Chevy Cavalier and am trying to replace the starter but think may have wire on wrong post is there anything that can help Like wiring diagram shows where wires go?

You're right to be cautious! Getting the starter wires wrong can damage your car's electrical system or even create a fire. A wiring diagram is absolutely crucial for this job.

Here's how to find the information you need:

1. Your Car's Repair Manual: The best source is a repair manual specific to your 1999 Chevy Cavalier. These manuals often have detailed wiring diagrams, showing exactly which wire goes to which terminal on the starter. You can often find these online (like on eBay or Amazon) or at auto parts stores. Look for one that specifically states it's for a 1999 Cavalier.

2. Online Resources: Websites like Haynes.com or Chilton.com often sell downloadable repair manuals. Some websites specializing in automotive repair information might have wiring diagrams available, but be cautious about their reliability.

3. Auto Parts Store: Most auto parts stores (like AutoZone, Advance Auto Parts, Napa) have access to repair information, sometimes for free if you're a customer. They might have a wiring diagram printout or be able to look up the information on their computer systems. Take your car's VIN number with you for accurate results.

4. Online Forums: Searching online forums specific to Chevy Cavaliers (e.g., on dedicated car enthusiast websites) might uncover someone who's done the same repair and can offer guidance or even a picture of their starter wiring. However, treat this information with caution and always verify it with a reputable source.

Important Considerations When Using a Wiring Diagram:

* Identify Your Specific Engine: The wiring might be slightly different depending on the engine type in your Cavalier (e.g., 2.2L, 2.4L). Make sure the diagram matches your car's engine.

* Wire Colors: Pay close attention to the wire colors shown in the diagram. They are your key to correct installation.

* Battery Cable: The large, heavy gauge cable is always the positive (+) connection. The smaller cable is usually the negative (-) or control wire (from the ignition switch).

* Safety First: Disconnect the negative (-) battery cable before starting any electrical work.

If you are unsure at any point, do not proceed. It's better to seek professional help from a qualified mechanic than risk damaging your car. Incorrect wiring can lead to expensive repairs.
